10:4,5 The sheep follow him: for they know his voice. Also literally true in the East as all travelers testify, but a
stranger they will not follow, because his voice is strange. So true is it that when a traveler has changed dress with the shepherd for an experiment, they still have followed the disguised shepherd's voice and refused to listen to the voice of a stranger in the garb of their own shepherd.
10:5 They will not follow a stranger - One whom Christ hath not sent, who doth not answer the preceding description. Him they will not follow - And who can constrain them to it? But will flee from him - As from the plague. For they know not the voice of strangers - They cannot relish it; it is harsh and grating to them. They find nothing of God therein.
10:1-5 Here is a parable or similitude, taken from the customs of the East, in the management of sheep. Men, as creatures depending on their Creator, are called the sheep of his pasture. The church of God in the world is as a sheep-fold, exposed to deceivers and persecutors. The great Shepherd of the sheep knows all that are his, guards them by his providence, guides them by his Spirit and word, and goes before them, as the Eastern shepherds went before their sheep, to set them in the way of his steps. Ministers must serve the sheep in their spiritual concerns. The Spirit of Christ will set before them an open door. The sheep of Christ will observe their Shepherd, and be cautious and shy of strangers, who would draw them from faith in him to fancies about him.
