Isaiah 11:5 - Clarke's commentary and critical notes on the Bible

And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins. The girdle "The cincture" - All the ancient Versions, except that of Symmachus, have two different words for girdle in the two hemistichs. It is not probable that Isaiah would have repeated אזור azer, when a synonymous word so obvious as חגור chagor occurred. The tautology seems to have arisen from the mistake of some transcriber. The meaning of this verse is, that a zeal for justice and truth shall make him active and strong in executing the great work which he shall undertake. See note on Isaiah 5:27.
