1 Chronicles 20:1-2

MLV(i) 1 And it happened, at the time of the return of the year, at the time when kings go out to battle, that Joab led forth the army and wasted the country of the sons of Ammon and came and besieged Rabbah, but David remained at Jerusalem. And Joab killed* Rabbah and overthrew it.
2 And David took the crown of their king from his head and found it to weigh a talant of gold and there were precious stones in it. And it was set upon David's head and he brought out the spoil of the city, exceedingly much.
