Genesis 12:20

And Pharaoh commanded his men concerning him: and they sent him away, and his wife, and all that he had.

And Pharaoh commanded his men concerning him,.... His courtiers and servants, not to do him any hurt or injury in his person or substance; who he might suppose would be enraged at hearing how the king and they had been imposed upon and deceived; he ordered a guard about him while he was there, and to conduct him, and all that belonged to him, safely out of his dominions, as appears by what follows: but Dr. Lightfoot {m} is of opinion, that he gave charge to the Egyptians, making it as it were a law for the time to come, that they should not converse with Hebrews, nor with foreign shepherds, in any so near familiarity, as to eat or drink with them, which the Egyptians observed strictly ever after, Genesis 43:32

and they sent him away, and his wife, and all that he had; they did not drive him out by force, or in any disgraceful manner, but being committed to a guard of men, appointed by the king, he had safe conduct out of the land, with his family, and all that he had; all that he brought with him, and all the increase he had made there, and all the gifts he had received of the king. The Jews {n} interpret it of the writings and gifts he had given to Sarai; and they {o} observe a great likeness between Abram's descent into Egypt, his being there, and departure out of it, and that of his posterity in later times; as that they both went thither on account of a famine; that they both went down to sojourn there; and that they both went out with great substance; with other particulars observed by them.
