In the Hebrew the quick understanding seems more particularly to apply to the sense of smelling; intimating that the perception of Christ should be peculiarly so, and totally different from all others. Let the Reader look into the gospel, and mark the numberless instances in the ministry of Jesus, in his discerning the thoughts of the heart: John 2:24-25; Revelation 2:23. And what a lovely testimony the Prophet adds of this, when saying, that he shall not judge after the sight of his eyes: to show that he forms not his standard of decision by what men say, or by the outward appearance of things, as earthly judges do, and indeed can do no other. But his judgment shall be, because he readeth the heart. How sweet the thought, to his poor, and to his meek in the earth! Think of it, I beseech you, ye that are poor and exercised; and let this precious view of your Jesus always bring comfort with it!

3 And shall make him of quick understanding in the fear of the LORD: and he shall not judge after the sight of his eyes, neither reprove after the hearing of his ears:
4 But with righteousness shall he judge the poor, and reprovea with equity for the meek of the earth: and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked.
