Two more events involving "lying." God appeared to approve it in vss. 12:17 and 26:12.
Genesis 12:11-13
(11) And it came to pass, when he [Abram] was come near to enter into Egypt, that he said unto Sarai his wife, Behold now, I know that thou art a fair woman to look upon:
(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.
(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.
Genesis 12:17-18
(17) And the LORD plagued Pharaoh and his house with great plagues because of Sarai Abram's wife.
(18) And Pharaoh called Abram, and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?

Genesis 26:6-12
(6) And Isaac dwelt in Gerar:
(7) And the men of the place asked him of his wife; and he said, She is my sister: for he feared to say, She is my wife; lest, said he, the men of the place should kill me for Rebekah; because she was fair to look upon.
(8) And it came to pass, when he had been there a long time, that Abimelech king of the Philistines looked out at a window, and saw, and, behold, Isaac was sporting with Rebekah his wife.
(9) And Abimelech called Isaac, and said, Behold, of a surety she is thy wife: and how saidst thou, She is my sister? And Isaac said unto him, Because I said, Lest I die for her.
(10) And Abimelech said, What is this thou hast done unto us? one of the people might lightly have lien with thy wife, and thou shouldest have brought guiltiness upon us.
(11) And Abimelech charged all his people, saying, He that toucheth this man or his wife shall surely be put to death.
(12) Then Isaac sowed in that land, and received in the same year an hundredfold: and the LORD blessed him.
