Flock [1]

the correlative term to "pastor." "The way in which this term, or the language which implies it, invariably occurs in Scripture ( 1 Peter 5:2;  John 21:15), points out to the people that they are not properly the minister's flock (which would exalt him into the mediator between them and God), but Christ's." Eden, Church Dictionary, S.V.
