'Deal' in the Bible

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

And the men said unto her, Our life for yours, if ye utter not this our business; and it shall be, when Jehovah giveth us the land, that we will deal kindly and truly with thee.
