Rock (Heb. tsur), employed as a symbol of God in the Old Testament (1 Sam. 2:2; 2 Sam. 22:3; Isa. 17:10; Ps. 28:1; 31:2,3; 89:26; 95:1); also in the New Testament (Matt. 16:18; Rom. 9:33; 1 Cor. 10:4). In Dan. 2:45 the Chaldaic form of the Hebrew word is translated "mountain." It ought to be translated "rock," as in Hab. 1:12 in the Revised Version. The "rock" from which the stone is cut there signifies the divine origin of Christ. (See STONE.)
