Scofield Reference Notes (1917 Edition)Chapter 18
18:1 And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
18:23 And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?
Cf. Genesis 19:1. For significance of Abraham's tent, Hebrews 11:9,10.
Communion vs. Genesis 18:23, and intercession go together.
