[11]And when she had brought them unto him to eat, he took hold of her, and said unto her, Come lie with me, my sister.
[12]And she answered him, Nay, my brother, do not force me; for no such thing ought to be done in Israel: do not thou this folly.
[13]And I, whither shall I cause my shame to go? and as for thee, thou shalt be as one of the fools in Israel. Now therefore, I pray thee, speak unto the king; for he will not withhold me from thee.
[14]Howbeit he would not hearken unto her voice: but, being stronger than she, forced her, and lay with her. - Bible 2 Samuel 13:11-14 (bible)
Bible Genesis 19:30-36 (en) Incest (3) Lot's daughter had sex with him to give him descendants
[30]And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar: and he dwelt in a cave, he and his two daughters.
[31]And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth:
[32]Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father.
[33]And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose.
[34]And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father.
[35]And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose.
[36]Thus were both the daughters of Lot with child by their father. - Bible Genesis 19:30-36 (bible torah)
[15]When Judah saw her, he thought her to be an harlot; because she had covered her face.
[16]And he turned unto her by the way, and said, Go to, I pray thee, let me come in unto thee; (for he knew not that she was his daughter in law.) And she said, What wilt thou give me, that thou mayest come in unto me?
[17]And he said, I will send thee a kid from the flock. And she said, Wilt thou give me a pledge, till thou send it?
[18]And he said, What pledge shall I give thee? And she said, Thy signet, and thy bracelets, and thy staff that is in thine hand. And he gave it her, and came in unto her, and she conceived by him. - Bible Genesis 38:15-18 (bible torah)
