Isaiah 11:2

“And the Spirit of the Lord shall rest upon him, &c.] The rod and branch, the King Messiah, so qualifying him for his office, and the discharge of it. This shows that Christ’s kingdom is of a spiritual nature, and administered in a spiritual manner, for which he was abundantly furnished by the “Spirit of the Lord” resting on him; by whom is meant the third Person in the Trinity, so called, not because created by him, for not any created spirit is meant, but because he proceeded from him; he is the one Jehovah with him, a divine Person, truly God, yet distinct both from the Father and the Son; so that here is a clear proof of the trinity of Persons. Christ was filled with the Spirit from the…”

“Spirit of the Lord--JEHOVAH. The Spirit by which the prophets spake: for Messiah was to be a Prophet (Isa 61:1; Deu 18:15, Deu 18:18). Seven gifts of the Holy Spirit are specified, to imply that the perfection of them was to be in Him. Compare "the seven Spirits" (Rev 1:4), that is, the Holy Ghost in His perfect fulness: seven being the sacred number. The prophets had only a portion out of the "fulness" in the Son of God (Joh 1:16; Joh 3:34; Col 1:19). rest--permanently; not merely come upon Him (Num 11:25-26). wisdom-- (Co1 1:30; Eph 1:17; Col 2:3). understanding--coupled with "wisdom," being its fruit. Discernment and discrimination (Mat 22:18; Joh 2:25). counsel . . . might--the faculty…”

“And the Spirit of the Lord - The Spirit of Yahweh. Chaldee, ‘And there shall rest upon him the spirit of prophecy from before Yahweh.’ In the previous verse, the prophet had announced his origin and his birth. In this, he proceeds to describe his extraordinary endowments, as eminently holy, pure, and wise. There can be no doubt that reference is here had to the Holy Spirit, the third person of the sacred Trinity, as descending upon him in the fullness of his influences, and producing in him perfect wisdom, knowledge, and the fear of the Lord. The Spirit of Yahweh shall rest upon him - a Spirit producing wisdom, understanding, counsel, might, etc. All these are lit the Scriptures traced to…”

“Wisdom - It is not needful, exactly to distinguish these two gifts; it is sufficient that they are necessary qualifications for a governor, and a teacher, and it is evident they signify perfect knowledge of all things necessary for his own and peoples good, and a sound judgment, to distinguish between things that differ. Counsel - Of prudence, to give good counsel; and of might and courage, to execute it. Knowledge - Of the perfect knowledge of the whole will and counsel of God, as also of all secret things, yea of the hearts of men. Fear - A fear of reverence, a care to please him, and lothness to offend him. Isaiah 11:3”

“11:2 The Spirit of the Lord will rest on the Messiah. The succession of David’s line is guaranteed by the Spirit. The Messiah’s coming would bring justice and righteousness (11:4), peace (11:8), and the extension of the Kingdom to the nations (11:10; see also 32:15-16). • The promised Messiah would have great wisdom and understanding, like Solomon, as well as knowledge and the fear of the Lord (1 Kgs 3:28; 4:29; Prov 1:1-7; 2:6-7). • The Spirit of counsel and might alludes to Isa 9:6. The Messiah will be full of wisdom and will have the power to execute his righteous rule.”

“the Spirit: Isa 42:1, Isa 59:21, Isa 61:1; Num 11:25, Num 11:26; Mat 3:16; Joh 1:32, Joh 1:33, Joh 3:34; Act 10:38 the spirit of wisdom: Deu 34:9; Joh 14:17, Joh 15:26, Joh 16:13; Co1 1:30; Eph 1:17, Eph 1:18; Col 1:8, Col 1:9; Col 2:2, Col 2:3; Ti2 1:7; Jam 3:17, Jam 3:18 Isaiah 11:3”

“Jehovah acknowledges Him, and consecrates and equips Him for His great work with the seven spirits."And the Spirit of Jehovah descends upon Him, spirit of wisdom and understanding, spirit of counsel and might, spirit of knowledge and fear of Jehovah." "The Spirit of Jehovah" (ruach Yehovah) is the Divine Spirit, as the communicative vehicle of the whole creative fulness of divine powers. Then follow the six spirits, comprehended by the ruach Yehovah in three pairs, of which the first relates to the intellectual life, the second to the practical life, and the third to the direct relation to God. For chocmâh (wisdom) is the power of discerning the nature of things through the appearance, and…”
