Then Jesus went into the temple of God and drove out all those who bought and sold in the temple, and overturned the tables of the money changers and the seats of those who sold doves. 13 And He said to them, “It is written, ‘My house shall be called a house of prayer,’ but you have made it a ‘den of thieves.’”
14 Then the blind and the lame came to Him in the temple, and He healed them. 15 But when the chief priests and scribes saw the wonderful things that He did, and the children crying out in the temple and saying, “Hosanna to the Son of David!” they were indignant 16 and said to Him, “Do You hear what these are saying?”
And Jesus said to them, “Yes. Have you never read,
‘Out of the mouth of babes and nursing infants
You have perfected praise’?”
17 Then He left them and went out of the city to Bethany, and He lodged there. — Matthew 21:12-17.
Jesus’ quotation (v.16) of Psalm 8:2 to justify the children’s praises is astounding, for Psalm 8 says that God ordained worship for Himself from the lips of children. Jesus indirectly claims the prerogative of deity.
The religious leaders are indignant, as the blind and the lame come to Him in the recently purged temple and are healed and as children cry out ‘Hosanna to the Son of David!’ (Hosanna literally means ‘Save now’ and that is why Jesus has come.) Jesus refers them to yet another fulfilment of Scripture and leaves for Bethany (to stay in the household of Mary, Martha, and Lazarus — see John 12:1-11).
