Excellency of Jacob. — In the previous use of this remarkable expression (Amos 6:8) Jehovah is said to abhor it, but here He swears by it. The “excellency” which He abhorred was the miserable substitute which they had made for His great Name. Here He gives it the value which, in itself, it ought to possess.
