'Behave' in the Bible

And the people shall be oppressed, every one by another, and every one by his neighbour: the child shall behave himself proudly against the ancient, and the base against the honourable.

For a fool speaks folly, and his {mind} does iniquity: to {behave wickedly}, and to speak error concerning Yahweh, to leave [the] throat of [the] hungry empty, and he deprives [the] thirsty [of] drink.

The one who slaughters a bull also strikes down a man; the one who sacrifices a lamb also breaks a dog's neck; the one who presents an offering includes pig's blood with it; the one who offers incense also praises an idol. They have decided to behave this way; they enjoy these disgusting practices.
