'Grace' in the Bible

Then Joab, falling down on his face on the earth, gave the king honour and blessing; and Joab said, Today it is clear to your servant that I have grace in your eyes, my lord king, because the king has given effect to the request of his servant.

And the king said to Zadok, Take the ark of God back into the town: if I have grace in the eyes of the Lord, he will let me come back and see it and his House again:

Then the king said to Ziba, Truly everything which was Mephibosheth's is yours. And Ziba said, I give honour to my lord, may I have grace in your eyes, my lord, O king!
