Matthew Poole and continuators on Genesis 20:13

13 And it came to pass, when God caused me to wander from my fathers house, that I said unto her, This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother.

This word he useth, because God did not direct him to any certain place, but sent him out he knew not whither Heb. 11. 8. And being to travel and sojourn amongst persons of divers tempers and manners, and all Pagans, he thought this equivocal expression convenient for his security.
