'Thirty second' in the Bible

Moreover, from the appointed day I was made their governor in the land of Judah, from the twentieth year until the thirty-second year of King Artaxerxes--twelve years. My brothers and I did not eat the food [allowance] of the governor.

During all of this, I was not in Jerusalem because in the thirty-second year of Artaxerxes king of Babylon I went to the king. At the end of [some] days I asked permission from the king [to leave].
