And a third part [shall be] at the gate of Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, that it be not broken down.
ASV
and a third part shall be at the gate Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, and be a barrier.
