Deuteronomy 7:12

Wherefore it shall come to pass, if ye hearken to these judgments, and keep, and do them, that the LORD thy God shall keep unto thee the covenant and the mercy which he sware unto thy fathers:

It shall happen, because you listen to these ordinances, and keep and do them, that Yahweh your God will keep with you the covenant and the loving kindness which he swore to your fathers:

And it shall come to pass, because ye hearken to these ordinances, and keep and do them, that Jehovah thy God will keep with thee the covenant and the lovingkindness which he sware unto thy fathers:

`And it hath been, because ye hear these judgments, and have kept, and done them, that Jehovah thy God hath kept to thee the covenant and the kindness which He hath sworn to thy fathers,

If you listen to these ordinances and keep them carefully, then the LORD your God will keep His covenant and the loving devotion that He swore to your fathers.
