LOOM. An apparatus for weaving thread or yarn into cloth. The word is found twice in the RSV (Judg 16:14 KJV BEAM; Isa 38:12 KJV PINING SICKNESS). In Bible times three types of looms were in use. One was the horizontal loom, also called the ground loom, because it was laid out horizontally on the ground. It could be operated only in a stooping position. The other two types of loom were upright, and were operated from a sitting or a standing position. They differed in that in one type the threads of the warp hung from a crossbeam and were kept taut with weights attached to their lower ends; while in the other type the ends of the warp were attached to a revolving cloth beam, and therefore a much longer web could be woven.
