I'd like to find the name of the episode of Touched by an Angel when Monica literally shields a person who is being attacked.

List of Touched by an Angel episodes - Wikipedia, the free encyclopedia

"Monica reveals herself as an angel to Jean and physically shields Jean when she is attacked by fellow prisoners -- taking the painful blows herself."

Episode #426: "The Spirit Of Liberty Moon"

Original Air Date: May 17, 1998

Found it... finally... it's called The Spirit of Liberty Moon at the end of Season 4
