'Fell on His Knees' in the Bible

The king sent a third captain and his fifty soldiers. This third captain went up and fell on his knees before Elijah. He begged for mercy, "Prophet, please have respect for my life and for the lives of these fifty servants of yours.

Now as Jesus was starting out on his way, someone ran up to him, fell on his knees, and said, "Good teacher, what must I do to inherit eternal life?"
