Ezra 7:8-10

Ezra came to Jerusalem in the fifth month, during the seventh year of the king. He began the journey from Babylon on the first day of the first month and arrived in Jerusalem on the first day of the fifth month since the gracious hand of his God was on him. Now Ezra had determined in his heart to study the law of the LORD, obey it, and teach its statutes and ordinances in Israel.
