'Request' in the Bible

Now therefore seeing that I have come to speak this word to my lord the king, it is because the people have made me afraid: and your handmaid said, 'I will now speak to the king; it may be that the king will perform the request of his servant.'

Joab fell to the ground on his face, and did obeisance, and blessed the king. Joab said, "Today your servant knows that I have found favor in your sight, my lord, king, in that the king has performed the request of his servant."
