Matthew Poole and continuators on Isaiah 48:20

20. Go ye forth of Babylon : flee ye from the Caldeans, with a voice of singing , declare ye , tell this, utter it even to the end of the earth: say ye, The LORD hath redeemed his servant Iacob.

The imperative is here, as it is very frequently, put for the future, Ye shall go forth, &c. for this is not so much a command as a promise. Although this form of speech may be the rather used to intimate, That it was their duty to go forth, as well as God's promise to carry them forth.

With Joy and Songs of Praise to the Lord.

Publish God's wonderful Works on your behalf to all Nations.
