'Customs' in the Bible

You are not to live by the customs of the nations, whom I've cast away right in front of you. Because they did all of these things, I detested them.

To this very day, they still follow the former customs: they don't fear the LORD and they don't live in accordance with the statutes, ordinances, laws, or commandments that the LORD had given to the descendants of Jacob whom he renamed Israel

You keep Omri's statutes and observe the customs of the house of Ahab. Because you live according to their advice, I'll make you desolate and turn your inhabitants into an object of scorn. Therefore you will bear the shame of my people."
