'Ask' in the Bible

So David said, "Good! I will make an agreement with you. I ask only one thing from you. You will not see my face unless you bring Saul's daughter Michal when you come to visit me."

After all, there was no one in the entire house of my grandfather who did not deserve death from my lord the king. But instead you allowed me to eat at your own table! What further claim do I have to ask the king for anything?"
