'Years' in the Bible

Moreover from the time that I was appointed to be their governor in the land of Judah, from the twentieth year even to the two and thirtieth year of Artaxerxes the king, [that is], twelve years, I and my brothers have not eaten the bread of the governor.

"Yes, forty years you sustained them in the wilderness. They lacked nothing. Their clothes didn't grow old, and their feet didn't swell.

Yet many years you put up with them, and testified against them by your Spirit through your prophets. Yet would they not give ear. Therefore you gave them into the hand of the peoples of the lands.
