Jehovah Shepherding His Sheep - Psalm 23 by Joel Beeke and published by Reformation Heritage Books.
Sheep are mentioned 176 times, lambs 164 times, and shepherds 80 times in Scripture. No mention of the Shepherd-sheep metaphor is so well-known as Psalm 23. Though three millennia have passed since the sweet singer of Israel first sang about the shepherd care of God, this psalm still lends itself today to profound truths and invaluable lessons. Shepherding practices in Biblical times underscore that this psalm poignantly describes the unchanging spiritual life of communion between the Chief Shepherd, Jesus Christ, and His flock, the living church of God"
