'Years' 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.

Forty years you sustained them in the desert--they were not in need. Their clothing did not wear out and their feet did not swell.

You were patient toward them for many years, and you have warned them by your spirit through the hand of your prophets, but they did not listen. So you gave them into the hand of the nations of the lands.
