Ezekiel 4:2 - Clarke's commentary and critical notes on the Bible

And lay siege against it, and build a fort against it, and cast a mount against it; set the camp also against it, and set battering rams against it round about. Battering rams - כרים carim. This is the earliest account we have of this military engine. It was a long beam with a head of brass, like the head and horns of a ram, whence its name. It was hung by chains or ropes, between two beams, or three legs, so that it could admit of being drawn backward and forward some yards. Several stout men, by means of ropes, pulled it as far back as it could go, and then, suddenly letting it loose, it struck with great force against the wall which it was intended to batter and bring down. This machine was not known in the time of Homer, as in the siege of Troy there is not the slightest mention of such. And the first notice we have of it is here, where we see that it was employed by Nebuchadnezzar in the siege of Jerusalem, A.M. 3416. It was afterwards used by the Carthaginians at the siege of Gades, as Vitruvius notes, lib. 10 c. 19, in which he gives a circumstantial account of the invention, fabrication, use, and improvement of this machine. It was for the want of a machine of this kind, that the ancient sieges lasted so long; they had nothing with which to beat down or undermine the walls.
