Misinterpretations often take 'firstborn' literally as implying Jesus was created or the first of God's creations, as in some non-trinitarian views, overlooking the biblical idiom for supremacy and inheritance rights rather than chronological origin. Others restrict the promise to Solomon or David alone, ignoring its prophetic messianic scope within the Davidic covenant, or misconstrue it as promoting human kingship over divine sovereignty.
Psalms 89:27
King James Version (1769)
27 Also I will make him my firstborn, higher than the kings of the earth.
Psalm 89:27 is part of God's covenant promise to David, declaring that He will appoint David's heir as His firstborn, granting him preeminence and authority surpassing all earthly kings. This emphasizes divine sonship in the sense of exalted position and inheritance, ensuring the enduring stability of David's throne through a chosen successor, ultimately fulfilled in Jesus Christ as the eternal King of kings.
