Idolatry can be anything or writing or teaching that takes you away from God, or from his word, his Torah which leads you away from HIM.
Hello LuLav,
I believe the gentiles or nations mentioned in jeremiah 16:9 are the lost tribes of Israel that were scattered amongst all nations that have not yet returned to the land given to them by GOD.
these lost tribes have become the gentiles, they were assimilated to other cultures and have lost their ways lost their GOD followed other teachings, religions other gods (ex: money) and were deceived. However the lord knows exactly who they are and will gather them again after the second coming of the messiah.
Jer 16:13 Therefore will I cast you out of this land into a land that ye know not, neither ye nor your fathers; and there shall ye serve other gods day and night; where I will not shew you favour.
Jer 16:14 Therefore, behold, the days come, saith the LORD, that it shall no more be said, The LORD liveth, that brought up the children of Israel out of the land of Egypt;
Jer 16:15 But, The LORD liveth, that brought up the children of Israel from the land of the north, and from all the lands whither he had driven them: and I will bring them again into their land that I gave unto their fathers.
Jer 16:16 Behold, I will send for many fishers, saith the LORD, and they shall fish them; and after will I send for many hunters, and they shall hunt them from every mountain, and from every hill, and out of the holes of the rocks.
Jer 16:17 For mine eyes are upon all their ways: they are not hid from my face, neither is their iniquity hid from mine eyes.
Jer 23:3 And I will gather the remnant of my flock out of all countries whither I have driven them, and will bring them again to their folds; and they shall be fruitful and increase.
Jer 23:4 And I will set up shepherds over them which shall feed them: and they shall fear no more, nor be dismayed, neither shall they be lacking, saith the LORD.
Jer 23:5 Behold, the days come, saith the LORD, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth.
(This applies to the second coming of Christ, in bold, above)
Jer 23:6 In his days Judah shall be saved, and Israel shall dwell safely: and this is his name whereby he shall be called, THE LORD OUR RIGHTEOUSNESS.
Jer 23:7 Therefore, behold, the days come, saith the LORD, that they shall no more say, The LORD liveth, which brought up the children of Israel out of the land of Egypt;
Jer 23:8 But, The LORD liveth, which brought up and which led the seed of the house of Israel out of the north country, and from all countries whither I had driven them; and they shall dwell in their own land.
this, I believe is the second exodus the return of the remnants of the lost tribes back to Israel.
I have received some insights or was warned many many times for many days from the lord in 2017 about the exodus then again with insistance in 2018 about jacob's troubles. we are at the very beginning of these end times events;
Jer 30:2 Thus speaketh the LORD God of Israel, saying, Write thee all the words that I have spoken unto thee in a book.
Jer 30:3 For, lo, the days come, saith the LORD, that I will bring again the captivity of my people Israel and Judah, saith the LORD: and I will cause them to return to the land that I gave to their fathers, and they shall possess it.
Jer 30:4 And these are the words that the LORD spake concerning Israel and concerning Judah.
Jer 30:5 For thus saith the LORD; We have heard a voice of trembling, of fear, and not of peace.
Jer 30:6 Ask ye now, and see whether a man doth travail with child? wherefore do I see every man with his hands on his loins, as a woman in travail, and all faces are turned into paleness?
Jer 30:7 Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble; but he shall be saved out of it.
Jacob's trouble is also linked with prophecy in the book of Daniel.
Blessings,
