'Years' in the Bible

Now in the second year of their coming unto the house of God at Jerusalem, in the second month, began Zerubbabel the son of Shealtiel, and Jeshua the son of Jozadak, and the rest of their brethren the priests and the Levites, and all they that were come out of the captivity unto Jerusalem, and appointed the Levites, from twenty years old and upward, to have the oversight of the work of the house of Jehovah.

And thus they returned us answer, saying, We are the servants of the God of heaven and earth, and are building the house that was builded these many years ago, which a great king of Israel builded and finished.
