'Kindly' in the Bible

Now therefore, please swear to me by the Lord, since I have dealt kindly with you, that you also will deal kindly with my father’s household, and give me a pledge of truth,

So the men said to her, “Our life for yours if you do not tell this business of ours; and it shall come about when the Lord gives us the land that we will deal kindly and faithfully with you.”
