'Hand of the Lord' in the Bible

This Ezra went up from Babylon, and he was a scribe skilled in the law of Moses, which the Lord God of Israel had given; and the king granted him all he requested because the hand of the Lord his God was upon him.

and has extended lovingkindness to me before the king and his counselors and before all the king’s mighty princes. Thus I was strengthened according to the hand of the Lord my God upon me, and I gathered leading men from Israel to go up with me.
