"Daniel 14:33-42
New Revised Standard Version Catholic Edition

³³ Now the prophet Habakkuk was in Judea; he had made a stew and had broken bread into a bowl, and was going into the field to take it to the reapers. ³⁴ But the angel of the Lord said to Habakkuk, “Take the food that you have to Babylon, to Daniel, in the lions’ den.” ³⁵ Habakkuk said, “Sir, I have never seen Babylon, and I know nothing about the den.” ³⁶ Then the angel of the Lord took him by the crown of his head and carried him by his hair; with the speed of the wind^\)^a\) he set him down in Babylon, right over the den.

³⁷ Then Habakkuk shouted, “Daniel, Daniel! Take the food that God has sent you.” ³⁸ Daniel said, “You have remembered me, O God, and have not forsaken those who love you.” ³⁹ So Daniel got up and ate. And the angel of God immediately returned Habakkuk to his own place.

⁴⁰ On the seventh day the king came to mourn for Daniel. When he came to the den he looked in, and there sat Daniel! ⁴¹ The king shouted with a loud voice, “You are great, O Lord, the God of Daniel, and there is no other besides you!” ⁴² Then he pulled Daniel^\)^b\) out, and threw into the den those who had attempted his destruction, and they were instantly eaten before his eyes."

TL;DR: the guy being joinked up by the angel is a prophet and he is bringing daniel food
