Genesis 18:33ESV·traditional attribution

And the LORD went his way, when he had finished speaking to Abraham, and Abraham returned to his place.

Matthew Henry Presbyterian @wholebiblehenry

Communion with God is kept up by the word and by prayer. In the word God speaks to us; in prayer we speak to him. God had revealed to Abraham his purposes concerning Sodom; now from this Abraham takes occasion to speak to God on Sodom's behalf. Note, God's word then does us good when it furnishes us with matter for prayer and excites us to it.

And the Lord went his way, as soon as he had left communing with Abraham,.... It is great and wonderful condescension for God to commune with a creature; it is an act of sovereignty how long he will continue to do so; communion with him always is not to be expected in this life; he communes for a while, and then leaves off and goes...

ABRAHAM'S INTERCESSION. (Gen 18:23-33) Abraham drew near, and said, &c.--The scene described is full of interest and instruction--showing in an unmistakable manner the efficacy of prayer and intercession. (See also Pro 15:8; Jam 5:16). Abraham reasoned justly as to the rectitude of the divine procedure (Rom 3:5-6), and many guilty cities and nations have been spared on account of God's people (Mat 5:13; Mat 24:22).
