Genesis 12:12
Therefore it shall come to pass, when the Egyptians shall see thee, that they shall say, This is his wife: and they will kill me, but they will save thee alive.
Therefore it shall come to pass, when the Egyptians shall see thee,.... Who were a lustful people, and whose eyes would soon be fastened upon, and be taken with the beauty of Sarai:
that they shall say, This is his wife; this beautiful woman is such a man's wife:
and they will kill me, but they will save thee alive; so great a regard had they in those times, and even in Heathen countries, to the laws of marriage, that they chose rather to be guilty of murder than of adultery, though a lustful people; and therefore would, as Abram feared, take away his life, that it might be free and lawful for them to marry Sarai.
