Leviticus 20:20-23

²⁰If a man has sex EUP with his aunt, he has dishonored his uncle. I will punish both of them by causing them to die without having any children.

²¹If a man marries his brother's wife while his brother is still living, that is disgraceful. He has dishonored his brother; and they both will die without having any children.

²²Obey all my laws/decrees DOU carefully, in order that you will not be forced to leave MET the land to which I am bringing you.

²³Do not imitate/adopt the customs of the people of the land from which I will expel them as you advance. I hated them because they did all those things.
