'Hand of the Lord' in the Bible

This Ezra went up from Babylon; and he was a ready scribe in the law of Moses, which the LORD God of Israel had given: and the king granted him all his request, according to the hand of the LORD his God upon him.

And hath extended mercy unto me before the king, and his counsellers, and before all the king's mighty princes. And I was strengthened as the hand of the LORD my God was upon me, and I gathered together out of Israel chief men to go up with me.
