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; Ps 31:2, Ps 31:3; Ps 89:26; Ps 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.)
