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:
And shall make him of quick understanding in the fear of the Lord - Hebrew, haricho; literally, 'quick-scented in the fear of Yahweh;' endowed with a singular sagacity in discerning the genuine principle of religious fear of God, when it lies dormant in the yet unawakened sinner (Matthew 12:20; Acts 10:1; Acts 16:14) (Horsley). But Maurer, 'He shall delight in the fear of God.' The Hebrew means, to delight in the odours of anything (Exodus 30:38; Amos 5:21, "I will not smell in your solemn assemblies"); 'smell,' - i:e., delight in.
He shall not judge after the sight of his eyes - according to mere external appearances (John 7:24, "Judge not according to the appearance, but judge righteous judgment;" John 8:15; James 2:1; 1 Samuel 16:7). Herein Messiah is represented a just Judge and Ruler (Deuteronomy 1:16-17).
Neither reprove - decide, as the parallelism shows.
After the hearing of his ears - by mere plausible hearsays, but by the true merits of each case, which He "knew from the beginning" (John 6:64; Revelation 2:23).
