Heb. torah, denoting all the revealed will of God. This is the common Biblical term for the inspired writings of Scripture, particularly those of Moses (see on Num. 19:14; Deut. 4:44; 30:10; 31:9; Prov. 3:1; see Vol. I, pp. 37, 38). Isaiah directs men away from the words and wisdom of devils and men to the revealed wisdom of God. The prophets of God were His witnesses, or spokesmen, and the “testimony” they bore was His message of wisdom and life. Isaiah here directs men to the Word of God as the standard of truth and the guide to right living. God has revealed Himself in His Word.

 Whatever men may speak that is not in harmony with that Word has “no light” in it (see on ch. 50:10, 11).
