Genesis 18:33

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 his way, see ( Jeremiah 14:8 ) ; the Son of God in an human form, as soon as he had done talking with Abraham, perhaps disappeared to him, and went his way to Sodom, for there we find him in the next chapter:

and Abraham returned unto his place;
to his tent in the plains of Mamre, waiting to observe or hear what would be the issue and event of things respecting Sodom and Gomorrah.
