Genesis 15:8

And he said, LORD God, whereby shall I know that I shall inherit it?

He said, "Lord Yahweh, how will I know that I will inherit it?"

And he said, O Lord Jehovah, whereby shall I know that I shall inherit it?

and he saith, `Lord Jehovah, whereby do I know that I possess it?'

But Abram replied, “Lord GOD, how can I know that I will possess it?”
