Genesis 12:12

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.
