Command to Depart Babylon in Purity

Isaiah 52:11-12

Depart ye, depart ye, go ye out from thence, touch no unclean thing; go ye out of the midst of her; be ye clean, that bear the vessels of the LORD.

For ye shall not go out with haste, nor go by flight: for the LORD will go before you; and the God of Israel will be your rereward.
