'My Covenant' in the Bible

But I will remember My covenant with you in the days of your youth, and I will establish to you an everlasting covenant.

And I will establish My covenant with you; and you shall know that I am Jehovah;

Therefore so says the Lord Jehovah: As I live, surely My oath that he has despised, and My covenant that he has broken, I will even repay it on his own head.

that you have brought strangers, uncircumcised in heart and uncircumcised in flesh, to be in My sanctuary, to profane it, even My house, when you offer My bread, the fat and the blood. And they have broken My covenant because of all your abominations.
