I need help with this latin sentence?

Quintus, seeing this very old ceremony, was deeply moved. He turned to the statue of Apollo, which was in the last part of the temple; he lifted his hands to the sky and begged the gods to favor him. At the same time he will know this: he is to become poet and prophet of Apollo. He exited the temple in silence and descended down from the hill with Pompeius. Near the road was the Fountain of Castalius, Priest of Apollo and the Muses. Quintus stopped and drank some water.
