Jamieson, Fausset and Brown on 1 Peter 2:25

25. (Is 53:6.)

For--Assigning their natural need of healing (1Pe 2:24).

now--Now that the atonement for all has been made, the foundation is laid for individual conversion: so "ye are returned," or "have become converted to," &c.

Shepherd and Bishop--The designation of the pastors and elders of the Church belongs in its fullest sense to the great Head of the Church, "the good Shepherd." As the "bishop" oversees (as the Greek term means), so "the eyes of the Lord are over the righteous" (1Pe 3:12). He gives us His spirit and feeds and guides us by His word. "Shepherd," Hebrew, "Parnas," is often applied to kings, and enters into the composition of names, as "Pharnabazus."
