Nehemiah 2:7-8

Further, I said to the king, If it is the king's pleasure, let letters be given to me for the rulers across the river, so that they may let me go through till I come to Judah; And a letter to Asaph, the keeper of the king's park, so that he may give me wood to make boards for the doors of the tower of the house, and for the wall of the town, and for the house which is to be mine. And the king gave me this, for the hand of my God was on me.
