Evangelical Heritage Version

²⁰ Now I know without a doubt that you will become king, and that the kingship over Israel will be established in your hand. ²¹ So swear to me now by the Lord that you will not cut off my descendants after me and that you will not destroy my name from my father’s house.”

²² David promised this to Saul with an oath.
