Context

41And that I also have walked contrary unto them, and have brought them into the land of their enemies; if then their uncircumcised hearts be humbled, and they then accept of the punishment of their iniquity:

42Then will I remember my covenant with Jacob, and also my covenant with Isaac, and also my covenant with Abraham will I remember; and I will remember the land.

43The land also shall be left of them, and shall enjoy her sabbaths, while she lieth desolate without them: and they shall accept of the punishment of their iniquity: because, even because they despised my judgments, and because their soul abhorred my statutes.

44And yet for all that, when they be in the land of their enemies, I will not cast them away, neither will I abhor them, to destroy them utterly, and to break my covenant with them: for I am the LORD their God.

45But I will for their sakes remember the covenant of their ancestors, whom I brought forth out of the land of Egypt in the sight of the heathen, that I might be their God: I am the LORD.
