Bereshis 12:11-13

Orthodox Jewish Bible

¹¹ And it came to pass, when he was about to enter into Mitzrayim, that he said unto Sarai his isha, Hinei now, I know that thou art an isha yafeh to look upon;

¹² Therefore it shall come to pass, when the Egyptians shall see thee, that they shall say, This is his isha; and they will kill me, but they will save thee alive.

¹³ Say, now, thou art my achot; that it may be well with me for thy sake; and my nefesh shall live on account of thee.
