'Hand of the Lord' in the Bible

This Ezra was a perfect scribe in the law of Moses, which the LORD God of Israel did give. And the king gave him all that he required, according to the hand of the LORD his God upon him.

and hath inclined his mercy unto me in the presence of the king, and his counselors, and before all the king's high estates. And I was comforted, according to the hand of the LORD my God over me, and so gathered I the heads of Israel together, that they might go up with me.
