'Year' in the Bible

And when he had his hair cut, (which he did at the end of every year, because of the weight of his hair;) the weight of the hair was two hundred shekels by the king's weight.

In the days of David they were short of food for three years, year after year; and David went before the Lord for directions. And the Lord said, On Saul and on his family there is blood, because he put the Gibeonites to death.
