Isaiah 52:11 - Ellicott's Commentary On The Whole Bible

Depart ye... — The command is addressed to the exiles in Babylon. They are not to plunder or carry off spoil that would render them unclean. They are to bring only “the vessels of Jehovah,” i.e., the gold and silver which had been taken from His temple, and which Cyrus restored by them (Ezra 1:7). In this case the bearers are the Levites. Commonly, however, the phrase is used of “armour-bearers,” and this meaning is given to it by many commentators, as pointing to the whole body of the people as filling that function for the great king (1 Kings 14:27-28).
