'My Covenant' in the Bible

And I remembered my covenant with thee in the days of thy youth, and I set up to thee an eternal covenant

And I set up my covenant with thee, and thou knewest that I am Jehovah.

For this, thus said the Lord Jehovah: I live, if not mine oath which he despised, and my covenant which he brake, and I gave it upon his head.

In your bringing in the sons of the stranger, uncircumcised of heart and uncircumcised of flesh, to be in my holy place to profane it, my house, in your bringing near my bread, the fat and the blood, and they will break my covenant by all your abominations.
