Jeremiah 8:17 Meaning and Commentary

Jeremiah 8:17

For, behold, I will send serpents, cockatrices, among you,
&c.] The Chaldeans, comparable to these noxious and hurtful creatures, because of the mischief they should do unto them. The Targum is,

``for, lo, I will raise up against you people that kill as the destroying serpents.''

These were raised up by the Lord, and sent by him, just as he sent fiery serpents among the Israelites in the wilderness, when they sinned against him; there literally, here metaphorically. Which will not be charmed:
Jarchi says, at the end of seventy years a serpent becomes a cockatrice, and stops its ear, that it will not hearken to the voice of the charmer, according to ( Psalms 58:4 Psalms 58:5 ) , the meaning is, that these Chaldeans would not be diverted from their purposes in destroying of the Jews by any arts or methods whatever; as not by force of arms, so not by good words and entreaties, or any way that could be devised. And they shall bite you, saith the Lord;
that is, kill them, as the Targum interprets it; for the bite of a serpent is deadly.

Jeremiah 8:17 In-Context

15 We hoped for peace, but no good has come, for a time of healing, but there was only terror.

16 The snorting of enemy horses is heard from Dan. At the sound of the neighing of mighty steeds, the whole land quakes. They come to devour the land and everything in it, the city and all who dwell in it.

17 “For behold, I will send snakes among you, vipers that cannot be charmed, and they will bite you,” declares the LORD.

18 My sorrow is beyond healing; my heart is faint within me.

19 Listen to the cry of the daughter of my people from a land far away: “Is the LORD no longer in Zion? Is her King no longer there?” “Why have they provoked Me to anger with their carved images, with their worthless foreign idols?”
