'Flock' in the Bible

Take heed, therefore, to yourselves, and to all the flock, in which the Holy Spirit has made you overseers, to shepherd the assembly of the Lord and God which he purchased with his own blood.

For I know that after my departure, vicious wolves will enter in among you, not sparing the flock.

What soldier ever serves at his own expense? Who plants a vineyard, and doesn't eat of its fruit? Or who feeds a flock, and doesn't drink from the flock's milk?

Shepherd the flock of God which is among you, exercising the oversight, not under compulsion, but voluntarily, not for dishonest gain, but willingly;

neither as lording it over those entrusted to you, but making yourselves examples to the flock.
