Leviticus 18:1-11 NKJV

Romans 10:1-5 Brethren, my heart's desire and prayer to Go for Israel is that they may be saved.

For I bear them witness that they have zeal for God, but not according to knowledge.

For they being ignorant of God's righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God.

For Christ is the end of the law for righteousness to everyone who believes.

For Moses writes about the righteousness which is of the law, "The man who does those things shall live by them."

Deuteronomy 27:22-23 'Cursed is the one who lies with his sister, the daughter of his father or the daughter of his mother.' "And all the people shall say, 'Amen!"

'Cursed is the one who lies with his mother-in-law.' "And all the people shall say, 'Amen!"

Genesis 19:30-38 Then Lot went up out of Zoar and dwelt in the mountains, and his two daughters were with him; for he was afraid to dwell in Zoar.  And he and his two daughters dwelt in a cave.

Now the firstborn said to the younger, "Our father is old, and there is no man on the earth to come in to us a is the custom of all the earth.

"Come, let us make our father drink wine, and we will lie lie with him, that we may preserve the lineage of our father."

So they made their father drink wine that night. and the firstborn went in and lay with her father, and he did not know when she lay down or when she arose.

It happened on the next day that the firstborn said to the younger, "Indeed I lay with my father last night; let us make him drink wine tonight also, and you go in and lie with him, that we may preserve the lineage of our father."

Then they made their father drink wine that night also. And the younger arose and lay with him, and he did not know when she lay down or when she arose.

Thus both the daughters of Lot were with child by their father.

The firstborn bore a son and called his name Moab; he is the father of the Moabites to this day.

And the younger, she also bore a son and called his name Ben-Ammi; he is the father of the people of Ammon to this day.

1 Corinthians 5:1 It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles-- that a man has his father's wife!

Leviticus 20:17-21 'If a man takes his sister, his father's daughter or his mother's daughter, and sees her nakedness. It is a wicked thing. And they shall be cut off in the sight of their people. He as uncovered his sister's nakedness. He shall bear his quilt.

'If a man lies with a woman during her sickness and uncovers her nakedness, he has exposed her flow, and she has uncovered  the flow of her blood. Both of them shall be cut off from their people.

'You shall not uncover the nakedness of your mother's sister nor of your father's sister, for that would uncover his near of kin. They shall bear their guilt.

'If a man lies with his uncle's wife, he has uncovered his uncle's nakedness. They shall bear their sin, they shall die childless.

'If a man takes his brother's wife, it is a unclean thing. He has uncovered his brother's nakedness, They shall be childless.
