MKJV(i)
13 For when God made promise to Abraham, because He could swear by no greater, He swore by Himself,
14 saying, "Surely in blessing I will bless you, and in multiplying I will multiply you."
15 And so, after he had patiently endured, he obtained the promise.
16 For men truly swear by the greater, and an oath for confirmation is to them an end of all strife.
17 In this way desiring to declare more fully to the heirs of promise the immutability of His counsel, God interposed by an oath,
18 so that by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us,
