The place in which armour was deposited when not used (Neh. 3:19; Jer. 50:25). At first each man of the Hebrews had his own arms, because all went to war. There were no arsenals or magazines for arms till the time of David, who had a large collection of arms, which he consecrated to the Lord in his tabernacle (1 Sa,. 21:9; 2 Sam. 8:7-12; 1 Chr. 26:26, 27).
