And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.

People's New Testament

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.

Wesley's Notes

10:4 He goeth before them - In all the ways of God, teaching them in every point, by example as well as by precept; and the sheep follow him - They tread in his steps: for they know his voice - Having the witness in themselves that his words are the wisdom and the power of God. Reader, art thou a shepherd of souls? Then answer to God. Is it thus with thee and thy flock?

Matthew Henry's Concise Commentary

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.
