Engine

A term applied exclusively to military affairs in the Bible. The engines to which the term is applied in (2 Chronicles 26:15) were designed to propel various missiles from the walls of the besieged town. One, with which the Hebrews were acquainted, was the battering ram, described in (Ezekiel 26:9) and still more precisely in (Ezekiel 4:2; 21:22)
