'Year' in the Bible

And it came to pass, at the return of the year, at the time when kings go forth, that David sent Joab, and his servants with him, and all Israel; and they laid waste the land of the children of Ammon, and besieged Rabbah. But David abode at Jerusalem.

And there was a famine in the days of David three years, year after year; and David inquired of Jehovah. And Jehovah said, It is for Saul, and for his house of blood, because he slew the Gibeonites.
