'Law of Moses' in the Bible

Then Jeshua, the son of Jozadak, and his brothers the priests, and Zerubbabel, the son of Shealtiel, with his brothers, got up and made the altar of the God of Israel for burned offerings as is recorded in the law of Moses, the man of God.

This Ezra went up from Babylon; and he was a scribe, expert in the law of Moses which the Lord, the God of Israel, had given: and the king, moved by the Lord his God, gave him whatever he made request for.
