Isaiah 11:2 - Matthew Poole's English Annotations on the Holy Bible

The Spirit of the Lord; the Holy Ghost, wherewith he was anointed, Acts 10:38, and by whom his mother was overshadowed, Luke 1:35. Shall rest upon him; not only come upon him at certain times, as he did upon the prophets now and then at his pleasure, but shall have its constant and settled abode in him; although the same phrase be sometimes used of other prophets in an inferior sense, as Numbers 11:17 2 Kings 2:15. The Spirit of wisdom and understanding; which hath these perfections in itself, and confers them upon him. It is neither easy, nor at all necessary, exactly to distinguish these two gifts; it is sufficient that they are necessary qualifications for a governor, and for a teacher, both which offices were to meet in the Messiah; and it is evident that they signify a practical and perfect knowledge of all things necessary for the discharge of his trust, and for his own and people's good, and a sound judgment, to distinguish between things that differ. Of counsel and might; of prudence, to give good counsel; and of might and courage, to execute it; which are two necessary qualifications of a ruler. Of knowledge; of the perfect knowledge of the whole will and counsel of God, especially that which concerns the salvation of men, the prosecution whereof was his great work, as also of all secret and hidden things, yea, of the hearts of men, the knowledge whereof is ascribed to Christ. Matthew 9:4 Revelation 2:23. Of the fear of the Lord; not a fear of diffidence or horror, but of reverence; a care to please him, and loathness to offend him, which well became the Messiah towards his God and Father.
