New American Bible (Revised Edition)
18 If only you would attend to my commandments,
your peace would be like a river,
your vindication like the waves of the sea,
19 Your descendants like the sand,
the offspring of your loins like its grains,
Their name never cut off
or blotted out from my presence.
20 Go forth from Babylon, flee from Chaldea!
With shouts of joy declare this, announce it;
Make it known to the ends of the earth,
Say: “The Lord has redeemed his servant Jacob.
