Why does David call his heir "Lord"?
How can David call his descendant "Lord" in Luke 20:44?

Passage Under Consideration

“David calls Him ‘Lord.’ So how can He be David’s son?” (Luke 20:44). Jesus is citing Psalm 110:1 and confronting His hearers with the paradox that the Messiah is simultaneously David’s descendant and David’s sovereign.


Immediate Literary Context

Luke 20:41-44 records Jesus questioning the scribes in the temple during Passion Week. After silencing their challenges (vv. 20-40), He asks whose son the Messiah is. They answer, “The Son of David.” Jesus then quotes Psalm 110:1, forcing them to reconcile Davidic sonship with divine lordship.


Davidic Authorship Affirmed

Psalm superscriptions were considered canonical in second-temple Judaism. Jesus attributes Psalm 110 to David “in the Holy Spirit” (Mark 12:36), an endorsement of Davidic authorship and inspiration.


Key Terms Explored

• “LORD” (YHWH) = the covenant name of God.

• “My Lord” (’adoni in Hebrew; Kyrios mou in LXX) = a title of authority normally avoided for any superior except God or the king. David distinguishes two Persons: YHWH speaks to David’s Lord.


Theological Resolution: One Messiah, Two Natures

1. Descendant: According to the flesh Jesus comes “from the seed of David” (Romans 1:3). Matthew’s legal genealogy traces through Solomon; Luke’s biological line through Nathan, both converging in David ca. 1010 BC (Usshur).

2. Lord: John 1:1; Colossians 1:16 testify to Christ’s pre-existence and creative agency. Hence He precedes David ontologically while succeeding him genealogically.

“‘I, Jesus… am the Root and the Offspring of David’” (Revelation 22:16).


Messiah as Root and Branch in Prophecy

Isaiah 11:1 calls the coming Deliverer a “shoot from the stump of Jesse.”

Isaiah 11:10 labels Him “the Root of Jesse.”

Both images anticipate the paradox Jesus highlights.


Tri-Personal Godhead Implicit

YHWH speaks to the Messiah, yet both share divine status. Psalm 110:1 anticipates plurality within the one God, cohering with NT revelation of Father, Son, and Spirit (Matthew 28:19).


Historical Evidence That Jesus Is David’s Lord

• Resurrection: “He was raised on the third day according to the Scriptures” (1 Corinthians 15:4). Habermas’ “minimal facts” method isolates the empty tomb, post-mortem appearances, and early proclamation—all acknowledged by critical scholars and best explained by bodily resurrection, vindicating Jesus’ claim.

• Early Creed (1 Corinthians 15:3-7) dates within five years of the crucifixion, testifying that the earliest Christians confessed Jesus as “Lord” (Kyrios), the highest divine title in Greek.


Jewish Expectations vs. Jesus’ Claim

First-century Judaism anticipated a human Davidic warrior-king (cf. Psalms of Solomon 17-18). Jesus redirects this expectation by emphasizing the Messiah’s heavenly dignity in Psalm 110.


Archaeological Corroboration of David and the Promise

• Tel Dan Inscription (9th cent. BC) references the “House of David,” affirming a historical Davidic dynasty.

• Ketef Hinnom silver scrolls (7th cent. BC) preserve priestly benediction language contemporaneous with Davidic monarchy, illustrating the cultural matrix in which Psalm 110 appeared.


Expositional Flow of Psalm 110 Applied

Verse 1: Enthronement at God’s right hand → fulfilled in Christ’s ascension (Acts 2:34-36).

Verse 2: Rule extends from Zion → millennial expectation (Revelation 20:4-6).

Verse 4: Everlasting priesthood “after the order of Melchizedek” → realized in Jesus (Hebrews 7).


Philosophical Implications

Only One who is both fully divine and fully human can mediate between God and man (1 Timothy 2:5). The paradox Jesus poses dismantles purely human conceptions of Messiah and demands acknowledgment of His deity.


Practical Ramifications for the Reader

If even King David bows to his descendent, so must every creature. Romans 10:9 links confession of “Jesus is Lord” with salvation. The passage invites intellectual assent and heartfelt submission.


Summary Answer

David can call his descendant “Lord” because the Messiah is more than David’s biological heir; He is the eternal Son of God incarnate. Psalm 110 prophetically reveals a divine-human King-Priest. Jesus’ resurrection validates this claim, and manuscript, archaeological, prophetic, and historical evidence converge to confirm it.
