Chilton notes, "The sheepfold Jesus was thinking about was an open space surrounded by a wall, with but one opening and here the shepherd took up His position as the door. It was this that the sheep literally and actually came in and out through Him. Thus they were watched over, cared for, counted and examined to see if any were hurt. If they were hurt, the Good Shepherd would anoint with a healing oil to help facilitate healing in the sheep. He would know His sheep so well they would be named and the sheep would also know their shepherd’s voice. (pg. 49.)
