'Covenant of the Lord' in the Bible

and commanded the people: “When you see the ark of the covenant of the Lord your God carried by the Levitical priests, you must break camp and follow it.

when the ark of the covenant of the Lord of all the earth goes ahead of you into the Jordan.

If you break the covenant of the Lord your God, which He commanded you, and go and worship other gods, and bow down to them, the Lord’s anger will burn against you, and you will quickly disappear from this good land He has given you.”
