The Hebrews usually secured their doors by bars of wood or iron (Isa. 45:2; 1 Kings 4:3). These were the locks originally used, and were opened and shut by large keys applied through an opening in the outside (Judg. 3:24). (See KEY.)

Lock of hair (Judg. 16:13, 19; Ezek. 8:3; Num. 6:5, etc.).

Where European locks have not been introduced, the locks of eastern houses are usually of wood, and consist of a partly hollow bolt from fourteen inches to two feet long for external doors or gates, or from seven to nine inches for interior doors. The bold passes through a groove in a piece attached to the door into a socket in the door-post.
