'Covenant' in the Bible

Then I said, "Please, O LORD God of heaven, great and awesome God, who keeps his loving covenant with those who love him and obey his commandments,

When you perceived that his heart was faithful toward you, you established a covenant with him to give his descendants the land of the Canaanites, the Hittites, the Amorites, the Perizzites, the Jebusites, and the Girgashites. You have fulfilled your promise, for you are righteous.

"So now, our God -- the great, powerful, and awesome God, who keeps covenant fidelity -- do not regard as inconsequential all the hardship that has befallen us -- our kings, our leaders, our priests, our prophets, our ancestors, and all your people -- from the days of the kings of Assyria until this very day!

"Because of all of this we are entering into a binding covenant in written form; our leaders, our Levites, and our priests have affixed their names on the sealed document."

Please remember them, O my God, because they have defiled the priesthood, the covenant of the priesthood, and the Levites.
