And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD;
The Spirit of the Lord shall rest upon him - the Spirit of Yahweh. The Spirit by which the prophets spake, because Messiah was to be a Prophet (Isaiah 61:1; Deuteronomy 18:15; Deuteronomy 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 which are before His throne" (Revelation 1:4) - i:e., the Holy Spirit in His perfect fullness; seven being the sacred number. The prophets had only a portion out of the 'fulness' in the Son of God (John 1:16; John 3:34; Colossians 1:19).
Rest - permanently; not merely come upon Him (Numbers 11:25-26).
The spirit of wisdom - (1 Corinthians 1:30; Ephesians 1:17; Colossians 2:3.) And understanding - coupled with "wisdom," being its fruit. Discernment and discrimination. Compare, for instance, His replies to adversaries, Matthew 22:18; Mark 12:34; and His insight into man, John 2:25.
The spirit of counsel and might - the faculty of forming counsels, and that of executing them (Isaiah 28:29). "Counsellor" (Isaiah 9:6).
The spirit of knowledge - of the deep things of God (Matthew 11:27). The knowledge of Him gives us true knowledge (Ephesians 1:17).
And of the fear of the Lord - reverential, obedient fear. The first step toward true "knowledge" (Job 38:28; Psalms 111:10).
