'Covenant' in the Bible

and said, I beseech thee, O Jehovah, the God of heaven, the great and terrible God, that keepeth covenant and lovingkindness with them that love him and keep his commandments:

and foundest his heart faithful before thee, and madest a covenant with him to give the land of the Canaanite, the Hittite, the Amorite, and the Perizzite, and the Jebusite, and the Girgashite, to give it unto his seed, and hast performed thy words; for thou art righteous.

Now therefore, our God, the great, the mighty, and the terrible God, who keepest covenant and lovingkindness, let not all the travail seem little before thee, that hath come upon us, on our kings, on our princes, and on our priests, and on our prophets, and on our fathers, and on all thy people, since the time of the kings of Assyria unto this day.

And yet for all this we make a sure covenant, and write it; and our princes, our Levites, and our priests, seal unto it.

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