• Babylon destroyed in 539 BC typified the completion of the 70th year (End of the Flood) which is the destruction of Spiritual Babylon (The physical organized churches) and the rest of the entire unsaved world.
   

Jeremiah 25:12 And it shall come to pass, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, saith the LORD, for their iniquity, and the land of the Chaldeans, and will make it perpetual desolations.

• Babylon destruction in 539 BC typified the completion of a harvest outside of Judah where a remnant of typified believers were told to complete harvest (plant gardens) not in physical Judah, but in physical Babylon.
   

Jeremiah 29:28 For therefore he sent unto us in Babylon, saying, This captivity is long: build ye houses, and dwell in them; and plant gardens, and eat the fruit of them.

The end of Babylon the Flood typified the destruction of Spiritual Babylon (The physical organized churches) and the rest of the entire unsaved world:

Babylon destroyed at the end of 70 years:

Jeremiah 25:12 And it shall come to pass, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, saith the LORD, for their iniquity, and the land of the Chaldeans, and will make it perpetual desolations.

Babylon is pictured as the Flood:
 

Jeremiah 47:2 Thus saith the LORD; Behold, waters rise up out of the north, and shall be an overflowing flood, and shall overflow the land, and all that is therein; the city, and them that dwell therein: then the men shall cry, and all the inhabitants of the land shall howl.

Babylon as flood destroyed (end of flood):

Jeremiah 51:36 Therefore thus saith the LORD; Behold, I will plead thy cause, and take vengeance for thee; and I will dry up her sea, and make her springs dry.
Jeremiah 51:37 And Babylon shall become heaps, a dwellingplace for dragons, an astonishment, and an hissing, without an inhabitant.

The hebrew word [4599. mayan] translated fountain during the Flood of Noah's Day in Genesis 7:11 is akin to a spring or well. The destruction of Babylon the Flood is typified with her sea and springs made dry.

Genesis 7:11 | In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains [4599. mayan] of the great deep broken up, and the windows of heaven were opened.

Babylon's (the Flood) destruction typified the final destruction of the Spiritual Kingdom of Babylon (The physical organized churches) and the rest of the entire unsaved world (note that ever nation on earth is brought under judgment with the destruction of Spiritual Babylon, Jeremiah 25:11-26) .

Jeremiah 25:11 And this whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years.

Jeremiah 25:12 And it shall come to pass, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, saith the LORD, for their iniquity, and the land of the Chaldeans, and will make it perpetual desolations.

Jeremiah 25:13 And I will bring upon that land all my words which I have pronounced against it, even all that is written in this book, which Jeremiah hath prophesied against all the nations.

Jeremiah 25:14 For many nations and great kings shall serve themselves of them also: and I will recompense them according to their deeds, and according to the works of their own hands.

Jeremiah 25:15 ¶ For thus saith the LORD God of Israel unto me; Take the wine cup of this fury at my hand, and cause all the nations, to whom I send thee, to drink it.

Jeremiah 25:16 And they shall drink, and be moved, and be mad, because of the sword that I will send among them.

Jeremiah 25:17 Then took I the cup at the LORD’S hand, and made all the nations to drink, unto whom the LORD had sent me:

Jeremiah 25:18 To wit, Jerusalem, and the cities of Judah, and the kings thereof, and the princes thereof, to make them a desolation, an astonishment, an hissing, and a curse; as it is this day;

Jeremiah 25:19 Pharaoh king of Egypt, and his servants, and his princes, and all his people;

Jeremiah 25:20 And all the mingled people, and all the kings of the land of Uz, and all the kings of the land of the Philistines, and Ashkelon, and Azzah, and Ekron, and the remnant of Ashdod,

Jeremiah 25:21 Edom, and Moab, and the children of Ammon,

Jeremiah 25:22 And all the kings of Tyrus, and all the kings of Zidon, and the kings of the isles which are beyond the sea,

Jeremiah 25:23 Dedan, and Tema, and Buz, and all that are in the utmost corners,

Jeremiah 25:24 And all the kings of Arabia, and all the kings of the mingled people that dwell in the desert,

Jeremiah 25:25 And all the kings of Zimri, and all the kings of Elam, and all the kings of the Medes,

Jeremiah 25:26 And all the kings of the north, far and near, one with another, and all the kingdoms of the world, which are upon the face of the earth: and the king of Sheshach shall drink after them.

The enemy that comes during the Final Tribulation is Satan (the Flood):

Revelation 13:6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.

Revelation 13:7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.

Satan coming is as a flood:

Revelation 12:15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
 

God in his coming at the end of the heavens and earth is to destroy the Flood. The Sea in Revelation 21:1 is synonymous with the flood as Babylon is a picture of the enemy that comes as a flood in Jeremiah 47:2. The sea is also contrasted with the flood in Job 14:11.

Revelation 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.

Jeremiah 51:36 Therefore thus saith the LORD; Behold, I will plead thy cause, and take vengeance for thee; and I will dry up [ 2717. charab] her sea, and make her springs dry.

Jeremiah 47:2 Thus saith the LORD; Behold, waters rise up out of the north, and shall be an overflowing flood, and shall overflow the land, and all that is therein; the city, and them that dwell therein: then the men shall cry, and all the inhabitants of the land shall howl.

Job 14:11 As the waters fail from the sea, and the flood decayeth and drieth up:

Babylon destruction in 539 BC typified the completion of a final harvest :

The number 50 is identifiedwith the completion of a harvest cycle:

• 25 weeks of early and latter rain
• 25 weeks of harvest time 7 weeks from the day after Passover is Pentecost and 18 weeks from Pentecost to the Feast of Ingathering (Fall Harvest)

The jubille occuring at the end of 50 years typified the end of harvest activity and the increase of the land was tobe eaten:
 

Leviticus 25:10 And ye shall hallow the fiftieth year, and proclaim liberty throughout all the land unto all the inhabitants thereof: it shall be a jubile unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family.

Leviticus 25:11 A jubile shall that fiftieth year be unto you: ye shall not sow, neither reap that which groweth of itself in it, nor gather the grapes in it of thy vine undressed.

Leviticus 25:12 For it is the jubile; it shall be holy unto you: ye shall eat the increase thereof out of the field.

Leviticus 25:13 In the year of this jubile ye shall return every man unto his possession.

The number 17 is identifiedwith Judgment/Heaven:

Genesis 37:2 These are the generations of Jacob. Joseph, being seventeen years old, was feeding the flock with his brethren; and the lad was with the sons of Bilhah, and with the sons of Zilpah, his father’s wives: and Joseph brought unto his father their evil report.

A spiritual purchase of Land in Israel by Jeremiah for 17 shekels typified the acquisition of the eternal Kingdom or Heaven:

Jer. 32:9 And I bought the field of Hanameel my uncle’s son, that was in Anathoth, and weighed him the money, even seventeen shekels of silver.

The number 37 identified with Judgment/Heaven], and 37 [identified with judgment/and the summation of all periods that typified the end of Great Tribulation (1+8+6+0)+(5+3+9) +(2+0+1+2) =37]

The Number 37 is a factor of 185 (5 x 37) is identified with judgment:

Sennacherib (King Assyria- typified as Kingdom of Satan) dealt treacherously with Hezekiah (Isa. 33:1), and a second time within two years invaded his kingdom (2 Kings 18:17; 2 Chr. 32:9; Isa. 36). This invasion issued in the destruction of Sennacherib’s army. Hezekiah prayed to God, and “that night the angel of the Lord went out, and smote in the camp of the Assyrians 185,000 men. Interestingly in 2Kings 18:31, prior to the destruction of the 185,000 the King of Assyria solicits those in Jerusalem to join him (Satan's Kingdom, during the Great Tribulation the physical organized churches are under the rule of Satan) that they may eat of their own vine and fig, this is opposite of the vineyard that is owned by God, Luke 20:13-15.

2Kings 18:31 Hearken not to Hezekiah: for thus saith the king of Assyria, Make an agreement with me by a present, and come out to me, and then eat ye every man of his own vine, and every one of his fig tree, and drink ye every one the waters of his cistern:

Note: In the time line that Joseph was also 37 years old at that start of the dearth in 1879 BC - (the start of a 19-year period that typified Great Tribulation in Chanaan, Acts 7-11).
