And I will render unto Babylon and to all the inhabitants of Chaldea all their evil that they have done in Zion in your sight, saith the LORD.
I will render unto Babylon ... all their evil that they have done. The detail of particulars (Jeremiah 51:20-23) is in order to express the indiscriminate slaughters perpetrated by Babylon on Zion, which, in just retribution, are all to befall herself (Jeremiah 50:15; Jeremiah 50:29)
In your sight - addressed to the Jews.
