So that thou incline thine ear unto Wisdom,.... Hearken to Wisdom, that is, Christ; or rather to the instruction of Wisdom, which is the Gospel; so called, because it is the produce of divine wisdom, what the wisdom of man could never have devised, and which it opposes; and in which there is a most glorious display of the wisdom of God, in the justification and salvation of his people by Christ, Co1 2:6; and is worth listening unto with the greatest attention, which is what is designed by this expression; and apply thine heart to understanding; to a spiritual and experimental understanding of the Gospel, and the truths of it: for an inclination of the ear, without an application of the heart, which signifies the intenseness of the mind, an earnest and hearty desire after knowledge, will signify nothing; a hypocrite may seemingly hear with great attention, and show much affection, and yet his heart be after the world and the things of it, Eze 33:31; see Psa 119:112.
