Gn 18:1-15 Twice in a few verses Sarah hears “about this time next year” she’ll have a son. She first overhears the talking visitor tell Abraham that, and she laughs to herself at the possibility. The Lord confronts her about laughing; she becomes afraid and lies that she ever did. Meanwhile the Lord tells her what she already overheard (i.e. “about this time next year”).
Q#1: How and when did the trinity of visitors ever find out Sarah would be having a son?
Gn 18:16-33 "The men set out from there and looked down toward Sodom; Abraham was walking with them, to see them on their way”. ...“While the 2 men walked on farther toward Sodom, the Lord remained standing before Abraham” and He and Abraham talked. ..."The Lord departed as soon as He had finished speaking with Abraham, and Abraham returned home."
Q#2's: If we had 3 visitors and the Lord seeing Abraham, only 2 men walked farther toward Sodom, the Lord departed after speaking with Abraham, and Abraham went home, how can we account for a third visitor? Where did he go? Did he get lost?
