'Guard' in the Bible

Palal the son of Uzai [repaired] over against the turning [of the wall], and the tower that stands out from the upper house of the king, which is by the court of the guard. After him Pedaiah the son of Parosh [repaired].

Likewise at the same time said I to the people, "Let everyone with his servant lodge within Jerusalem, that in the night they may be a guard to us, and may labor in the day."

So neither I, nor my brothers, nor my servants, nor the men of the guard who followed me, none of us took off our clothes. Everyone took his weapon to the water.

I said to them, "Don't let the gates of Jerusalem be opened until the sun is hot; and while they stand guard, let them shut the doors, and you bar them: and appoint watches of the inhabitants of Jerusalem, everyone in his watch, with everyone near his house."

and above the gate of Ephraim, and by the old gate, and by the fish gate, and the tower of Hananel, and the tower of Hammeah, even to the sheep gate: and they stood still in the gate of the guard.
