Excellent - literally, “princely things.” The word is not the same as in marginal reference, and is elsewhere always used of persons (compare “captain” in 1 Samuel 9:16; 2 Samuel 5:2). The poetic style of this part of the book applies it here to the things taught, or to the character of the teaching.
