David is an Old Testament figure and his sons are the kings of Judah with rare exception. Still his progeny are mentioned twice as often in the New Testament period, a time when Judah had no Davidide monarchs. People in New Testament times are beside themselves in expectation of and reverence for a son of David. He turns out to be neither king in the normal sense, nor prophet, nor priest, but a sacrificial lamb.
God’s kingdom and civic obligations
24) When they came to Capernaum, those who collected the two-drachma tax came to Peter and said, “Does your teacher not pay the two-drachma tax?” 25) He said, “Yes.” And when he came into the house, Jesus spoke to him first, saying, “What do you think, Simon? From whom do the kings of the earth collect customs or poll-tax, from their sons or from strangers?” 26) When Peter said, “From strangers,” Jesus said to him, “Then the sons are exempt.” (Matthew 17:24-26, NASB)
This deliberation ended with Yeshua and Peter paying the toll, to avoid scandal.
Yahweh and David’s son
Solomon should come to mind due to his distinct reputation as successor of David. He was responsible for bringing David’s dream to reality, and yet he devastated the Davidide standard by worshipping other gods. When Christ said “Someone greater than Solomon is here” oppressed persons were already appealing to Him for mercy and calling him “Lord”.
As Jesus went on from there, two blind men followed Him, crying out, “Have mercy on us, Son of David!” When He entered the house, the blind men came up to Him, and Jesus said to them, “Do you believe that I am able to do this?” They said to Him, “Yes, Lord”Matthew 9:27-28, NASB
Neither Solomon nor the temple and its administration should come to mind after Christ displays the mercy that makes blind persons (not necessarily males) see. This approach to David’s son continued.
And two blind men sitting by the road, hearing that Jesus was passing by, cried out, “Lord, have mercy on us, Son of David!” (Matthew 20:30, NASB)
Receiving the king with highest praise
Mounted on donkey, riding into Zion, the word of God comes to pass. The highest praise possible concerns a saving king, not a levitical priest or prophet. The crowds and the children were not shouting “hallelujah” but “hosannah”, and not to Moses.
The crowds going ahead of Him, and those who followed, were shouting, “Hosanna to the Son of David; Blessed is He who comes in the name of the Lord; Hosanna in the highest!” (Matthew 21:9, NASB)
