I will make
This phrase indicates God's active role and sovereign will in the unfolding of His promises. It underscores the divine initiative and assurance that what God has purposed will indeed come to pass. The certainty of God's actions is a recurring theme throughout Scripture, emphasizing His faithfulness and omnipotence.

a horn
In biblical symbolism, a "horn" represents strength, power, and victory. The Hebrew word "qeren" often denotes a powerful ruler or king. In this context, it signifies the establishment of David's royal lineage and the messianic hope that arises from it. The horn is a prophetic symbol pointing to the ultimate fulfillment in Jesus Christ, the descendant of David, who embodies divine authority and kingship.

grow
The imagery of growth suggests a natural, organic process, indicating that God's promises unfold in His perfect timing. The growth of the horn for David signifies the flourishing of his dynasty and the eventual coming of the Messiah. This growth is not merely physical but also spiritual, reflecting the expansion of God's kingdom and His redemptive work through Christ.

for David
David, the shepherd-king, is central to God's covenantal promises. The reference to David highlights the Davidic Covenant, where God promised to establish David's throne forever (2 Samuel 7:16). This covenant finds its ultimate fulfillment in Jesus Christ, the Son of David, who reigns eternally. David's life and legacy are a testament to God's grace and the foreshadowing of the Messiah.

I have prepared
This phrase emphasizes God's foreknowledge and meticulous planning. The preparation of a lamp signifies God's provision and readiness to fulfill His promises. It reflects the divine orchestration of events leading to the coming of the Messiah, demonstrating that God's plans are deliberate and assured.

a lamp
A lamp symbolizes guidance, revelation, and hope. In the ancient Near Eastern context, a lamp provided light in darkness, representing God's presence and truth. The lamp for God's anointed one signifies the illumination and guidance that the Messiah brings to the world. Jesus, the Light of the World, fulfills this imagery by dispelling spiritual darkness and revealing God's salvation.

for My anointed one
The term "anointed one" refers to the Messiah, the chosen and consecrated servant of God. In Hebrew, "Messiah" means "anointed," and it is synonymous with the Greek "Christ." This phrase underscores the divine selection and empowerment of Jesus as the Savior and King. The anointing signifies God's favor and the outpouring of the Holy Spirit upon Jesus, who fulfills the messianic prophecies and brings redemption to humanity.

I have ordained a lamp.--Or, I have trimmed a lamp; the word used in connection with the sacred lights, under the express charge of Aaron and his sons (Exodus 27:21; Leviticus 24:2-3). But with this distinctly sacerdotal allusion we must also combine the special allusion to the Davidic dynasty, according to the promise (1Kings 11:36): "That David my servant may have a light (or, lamp, as here) always before me in Jerusalem." . . .
