Accordingly God also, in His desire to show more convincingly and beyond doubt to those who were to inherit the promise the unchangeableness of His purpose and plan, intervened (mediated) with an oath.
If we are faithless [do not believe and are untrue to Him], He remains true (faithful to His Word and His righteous character), for He cannot deny Himself.
In blessing I will bless you and in multiplying I will multiply your descendants like the stars of the heavens and like the sand on the seashore. And your Seed (Heir) will possess the gate of His enemies, [Heb. 6:13, 14; 11:12.]
God is not a man, that He should tell or act a lie, neither the son of man, that He should feel repentance or compunction [for what He has promised]. Has He said and shall He not do it? Or has He spoken and shall He not make it good?
[Earnestly] remember Abraham, Isaac, and Israel, Your servants, to whom You swore by Your own self and said to them, I will multiply your seed as the stars of the heavens, and all this land that I have spoken of will I give to your seed, and they shall inherit it forever.
So from one man, though he was physically as good as dead, there have sprung descendants whose number is as the stars of heaven and as countless as the innumerable sands on the seashore. [Gen. 15:5, 6; 22:17; 32:12.]
Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured or numbered; and instead of it being said to them, You are not My people, it shall be said to them, Sons of the Living God! [Rom. 9:26.]
