'Deal' in the Bible

Now therefore, please swear to me by Yahweh, since I have dealt kindly with you, that you also will deal kindly with my father's house, and give me a true token;

The men said to her, "Our life for yours, if you don't talk about this business of ours; and it shall be, when Yahweh gives us the land, that we will deal kindly and truly with you."
