The New John Gill Exposition of the Entire BibleLamentations 3:64
Render unto them a recompence, O Lord, according to the work
of their hands.
] The Septuagint and Vulgate Latin versions render this,
and the following verses, not as petitions, but as prophecies of what
should be; but they seem rather to be expressed by way of request; and
here, that God would deal with them according to the law of retaliation,
and requite them according to what they had done; that he would do to
them as they had done to the Lord's people, and others; and this is
ordered to be done particularly to the Chaldeans, or Babylonians,
(Jeremiah 50:15,29) .
