The Spirit of the Lord Yahweh is on me; because Yahweh has anointed me to preach good news to the humble; he has sent me to bind up the broken-hearted, to proclaim liberty to the captives, and the opening [of the prison] to those who are bound; (Isaiah 61:1, World English)
It is the Messiah (anointed one) who is prophetically depicted as saying the the spirit of the Lord Yahweh was upon him, and that it was Yahweh -- the God of Abraham, Isaac and Jacob -- who anointed the Messiah. (Psalm 45:7) This is in harmony with the New Testament: Matthew 3:16; Luke 4:18-21; John1:32-34; Acts 2:36; 4:27; 10:38; Hebrews 1:9.
In Isaiah 61:1, the Messiah is depicted as saying, "Yahweh sent me". This also is in harmony with other prophecies and the New Testament. It was indeed the God of Abraham, Isaac and Jacob (Exodus 3:14,15) who raised and glorified His Son. Jesus himself made references as to having been sent, and speaking on behalf of, the God of Abraham. — Deuteronomy 18:15-22; Matthew 22:32; 23:39; Mark 11:9,10; 12:26; Luke 13:35; 20:37; John 3:2,17,32-35; 4:34; 5:19,30,36,43; 6:57; 7:16,28; 8:26,28,38; 10:25; 12:49,50; 14:10; 15:15; 17:8,26; 20:17; Acts 2:22,34-36; 3:13-26; 5:30; Romans 15:6; 2 Corinthians 1:3; 8:6; 11:31; Colossians 1:3,15; 2:9-12; Hebrews 1:1-3; Revelation 1:1.
