Psalms 89:27

“Also I will make him my firstborn, etc.] Or, “make him the firstborn”; make him great, as Jarchi interprets it; give him the blessing, the double portion of inheritance: so Christ is made most blessed for ever, and has all spiritual blessings in his hands; and is heir of all things, and his people joint-heirs with him. Christ is God’s “firstborn”, or “first begotten”, (<580106>Hebrews 1:6), being begotten by him, and of him; and his firstbegotten, though none begotten after him; as the first that opened the womb, under the law, was called the firstborn, though none were ever born after; and in such sense his first begotten, as that he is his only begotten: and he is the firstborn, with…”

“Also I will make him my first-born - He shall be regarded and treated by me as the first-born son is in a family; that is, with distinguished favor and honor. Compare Genesis 27:19; Genesis 29:26; Exodus 4:22; Exodus 13:12; Jeremiah 31:9. See also the notes at Colossians 1:15, notes at Colossians 1:18. Higher than the kings of the earth - Than other kings; the most exalted among kings and rulers. This was entirely fulfilled in David, who occupied a pre-eminence among princes and rulers which no other king did: a prominence alike in his own personal character and his reign; in his relation to God; and in the fact that he was the ancestor of the Messiah, the “King of kings, and Lord of lords”…”

“My first - born - As he calls me father, Psa 89:26, so I will make him my son, yea my first - born; who had divers privileges above other sons. This and the following passage in some sort agree to David, but are properly accomplished in Christ. Higher - This also was in some sort accomplished in David, but more fully in the Messiah. Psalms 89:29”

“89:27 David would be the most eminent of earthly kings. The Hebrew word translated mightiest is the same as the designation for God as “Most High” (‘elyon).”
