Webster(i)
11 And it came to pass, when he had come near to enter into Egypt, that he said to Sarai his wife, Behold now, I know that thou art a fair woman to look upon:
12 Therefore it will come to pass, when the Egyptians shall see thee, that they will say, This is his wife: and they will kill me, but they will save thee alive.
13 Say, I pray thee, thou art my sister: that it may be well with me for thy sake; and my soul shall live because of thee.
