“And he said, Lord GOD, whereby shall I know that I shall inherit it?”
King James Version (KJV)
15:8 Whereby shall I know that I shall inherit it? - This did not proceed from distrust of God's power or promise, but he desired this, For the strengthening of his own faith. He believed, #Ge 15:6|, but here he prays, Lord help me against my unbelief, Now, he believed, but he desired a sign, to be treasured up against an hour of temptation. For the ratifying of the promise to his posterity, that they also might believe it.
