Jeremiah 12:1-6

The Problem of Unrighteous Prosperity. Jeremiah raises (for the first time in Hebrew literature) the problem of the prosperity of the unrighteous, apparently in connexion with his experiences at Anathoth. He ventures to complain (rather than plead) unto Yahweh, since He should award adversity to the evildoers who dishonour Him in their inner man (reins, see on Jeremiah 11:20), and he appeals for their punishment. God answers Jeremiah (Jeremiah 12:5) with the warning that he has worse trials to face than the troubles at Anathoth

Jeremiah 12:4 has little point in this context except for its close, He shall not see our latter end, which apparently means that Jeremiah will not live to see the vengeance desired. For this, however, LXX reads, God will not see our ways.

Jeremiah 12:5. thou art secure: the change of one letter gives the much better sense, thou fleest. the pride of Jordan denotes the semi-tropical jungle of the Jordan valley, marking the breadth of the river in flood, still the haunt of wild beasts; cf. Jeremiah 49:19; Zechariah 11:3. This was visible from Jeremiah's home, Anathoth.
