Psalms 21:7

“For the King trusteth in the Lord, etc.] That is, the King Messiah, as the Targum paraphrases it; he trusted in the Lord for his support and sustenance as man, for assistance and help in his time of trouble, and for deliverance out of it; he trusted in the Lord that he would hear him for himself, and for his people; and that he would glorify him with all glory, honour, majesty, and blessedness, before spoken of; (see <192208>Psalm 22:8-10 <235007> Isaiah 50:7,9 <431331>John 13:31,32); and through the mercy of the most High he shall not be moved; God the Father is the most High; Christ is called the Son of the Highest, and the Spirit the power of the Highest, (<420132>Luke 1:32,35); there is…”
