And it came to pass in the spring of the year, at the time when kings go out to battle, that David sent Joab, and his servants with him, and all Israel, and they laid waste the children of Ammon and besieged Rabbah. But David stayed at Jerusalem. Bible

“in the spring of the year.” The Hebrew reads, “at the return of the year,” a reference to springtime.

“his servants.” This refers to the officers and officials of the king, not his household servants or slaves.

“Rabbah.” The capital city of Ammon, now much bigger and renamed Amman.
