So in the seventh year of King Artaxerxes, he went up to Jerusalem with some of the Israelites, including priests, Levites, singers, gatekeepers, and temple servants. 8Ezra arrived in Jerusalem in the fifth month of the seventh year of the king. 9He had begun the journey from Babylon on the first day of the first month, and he arrived in Jerusalem on the first day of the fifth month, for the gracious hand of his God was upon him. 10For Ezra had set his heart to study the Law of the LORD, to practice it, and to teach its statutes and ordinances in Israel.
