'Legal' in the Bible

If the people of the land should ever tolerate that man when he gives any of his children [as a burnt offering] to Molech, and fail to put him to death [as My law requires],

If there is a man who lies [intimately] with his uncle’s wife, he has uncovered his uncle’s nakedness; they will bear their sin. They will die childless.

If a man takes his brother’s wife, it is a hated and unclean thing; he has uncovered his brother’s nakedness. They will be childless.

Only the Levites shall perform the service of the Tent of Meeting (tabernacle), and they shall bear their iniquity; it shall be a statute forever throughout your generations, that the Levites shall have no inheritance [of land] among the children of Israel.
