'My Covenant' in the Bible

I will establish My covenant with you, and you will know that I am Yahweh,

Therefore, this is what the Lord God says: “As I live, I will bring down on his head My oath that he despised and My covenant that he broke.

When you brought in foreigners, uncircumcised in both heart and flesh, to occupy My sanctuary, you defiled My temple while you offered My food—the fat and the blood. You broke My covenant by all your detestable practices.
