16 For people swear by something greater than themselves, and in all their disputes ^han oath is final for confirmation. 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.
