Ezra 7:9-10

For upon the first {day} of the first month began he to go up from Babylon, and on the first {day} of the fifth month came he to Jerusalem, according to the good hand of his God upon him. {began...: Heb. was the foundation of the going up} For Ezra had prepared his heart to seek the law of the LORD, and to do {it}, and to teach in Israel statutes and judgments.
