Isaiah 44:21

Remember these, O Jacob, O Israel,.... Remember these persons, these idolaters before spoken of; or these things, the gross idolatries they were guilty of, and loath and abhor them, shun and avoid them, and not imitate them, and do the same things: or remember that this was formerly your case, and admire the distinguishing grace of God, in turning you from idols to serve him: for by Jacob and Israel may be meant the spiritual Israel of God, or those from among the Gentiles called by the grace of God, and incorporated into Christian churches; see Isa 44:5:for thou art my servant: I have formed thee; thou art my servant: and therefore should serve the Lord, and him only, and not idols, for no man can serve two masters; moreover, these were formed by the Spirit and grace of God in regeneration for his service, and therefore ought cheerfully to engage therein, and abide in it, and never serve any other:O Israel, thou shalt not be forgotten of me; such as remember the Lord, and remember to serve him, he will remember, and not forget them, his love to them, his covenant with them, and the promises he has made them; he will not forget their persons, nor their service, their work and labour of love, which they have showed to his name.
