Who does Jesus testify of?

Matthew 11.7-11

As they departed, Jesus began to say to the multitudes concerning John: “What did you go out into the wilderness to see? A reed shaken by the wind? But what did you go out to see? A man clothed in soft garments? Indeed, those who wear soft clothing are in kings’ houses. But what did you go out to see? A prophet? Yes, I say to you, and more than a prophet. For this is he of whom it is written:

‘Behold, I send My messenger before Your face,Who will prepare Your way before You.’

“Assuredly, I say to you, among those born of women there has not risen one greater than John the Baptist; but he who is least in the kingdom of heaven is greater than he.
