Esias 44:21

21 Remember these things, O Jacob and Israel; for thou art my servant; I have formed thee my servant: and do thou, Israel, not forget me.

Esias 44:21 In-Context

19 And one has not considered in his mind, nor known in his understanding, that he has burnt up half of it in the fire, and baked loaves on the coals thereof and has roasted and eaten flesh, and of the rest of it he has made an abomination, and they worship it.
20 Know thou that their heart is ashes, and they err, and no one is able to deliver his soul: see, ye will not say, lie in my right hand.
21 Remember these things, O Jacob and Israel; for thou art my servant; I have formed thee my servant: and do thou, Israel, not forget me.
22 For behold, I have blotted out as a cloud thy transgressions, and thy sin as darkness: turn to me, and I will redeem thee.
23 Rejoice, ye heavens; for God has had mercy upon Israel: sound the trumpet, ye foundations of the earth: ye mountains, shout joy, ye hills, and all the trees therein: for God has redeemed Jacob, and Israel shall be glorified.
