Isaiah 11:3

And shall make him of quick understanding... — Better, he shall draw his breath in the fear of the Lord. It shall be, as it were, the very air in which he lives and breathes. Some commentators, however, interpret he shall find a sweet savour. The Hebrew word rendered “understanding” means primarily, as the margin shows, “scent” or “smell,” either as the organ or the object of perception.

He shall not judge after the sight of his eyes... — Earthly kings are apt to judge “according to the appearance” (John 7:24), and the reports of interested or corrupt advisers, but the true King shall “know what is in man” (John 2:25), and judge righteous judgment.
