Isaiah 45:17, 25

15 Verily thou art a God that hidest thyself, O God of Israel, the Saviour.
16 They shall be ashamed, and also confounded, all of them: they shall go to confusion together that are makers of idols.

22 Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.

37 Behold, I will gather them out of all countries, whither I have driven them in mine anger, and in my fury, and in great wrath; and I will bring them again unto this place, and I will cause them to dwell safely:

Jeremiah 32:40, 42
40. And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.
42 For thus saith the Lord; Like as I have brought all this great evil upon this people, so will I bring upon them all the good that I have promised them.

And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.

11 By this I know that thou favourest me, because mine enemy doth not triumph over me.
12 And as for me, thou upholdest me in mine integrity, and settest me before thy face for ever.
