'Thus' in the Bible

Thus you shall do to all the cities which are very far off from you, which are not of the cities of these nations.

even all the nations shall say, "Why has Yahweh done thus to this land? What does the heat of this great anger mean?"

Do you thus requite Yahweh, foolish people and unwise? Isn't he your father who has bought you? He has made you, and established you.
