'Catch' in the Bible

And the king riseth by night, and saith unto his servants, 'Let me declare, I pray you, to you that which the Aramaeans have done to us; they have known that we are famished, and they are gone out from the camp to be hidden in the field, saying, When they come out from the city, then we catch them alive, and unto the city we enter.'

And he saith, 'Catch them alive;' and they catch them alive, and slaughter them at the pit of the shearing-house, forty and two men, and he hath not left a man of them.
