'Covenant and Mercy' in the Bible

And thou shalt know that Jehovah thy God, he is God, the faithful God, who keepeth covenant and mercy to a thousand generations with them that love him and keep his commandments;

And he said, Jehovah, God of Israel! there is no God like thee, in the heavens above, or on the earth beneath, who keepest covenant and mercy with thy servants that walk before thee with all their heart;

and said, Jehovah, God of Israel! there is no God like thee, in the heavens or on the earth, who keepest covenant and mercy with thy servants that walk before thee with all their heart;

and said, I beseech thee, Jehovah, God of the heavens, the great and terrible God, that keepeth covenant and mercy for them that love him and keep his commandments.
