But he that entereth in by the door is the shepherd of the sheep.
Ver. 2. But he that entereth in by the door] That is, called by Christ to the office of his undershepherd. In physicis aer non faeit seipsum ignem, sed fit a superiori, saith Aquinas.
Is the shepherd of the sheep] To the which is required, that he be both learned and loving. This note ariseth out of the notation of the word here used. (Ποιμην quasi οιμην, of οις, a sheep, and μαω, to desire earnestly.)
