The Certainty of God’s Promise

13 For when God made a promise to Abraham, since he had no one greater by whom to swear, ^ehe swore by himself,

17 So when God desired to show more convincingly to ⁱthe heirs of the promise ^jthe unchangeable character of his purpose, ^khe guaranteed it with an oath, 18 so that by two unchangeable things, in which ^lit is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope ^mset before us.
