Acts 20:28-31
So, pay close attention to your [own] lives, and to all [members] of the flock [i.e., the congregation] of which the Holy Spirit has made you overseers [i.e., elders, shepherds or pastors]. Provide [spiritual] food for the church of the Lord which He purchased by [shedding] His own blood.
1 Timothy 4:13-16
Until I come [to you], pay attention to the [public] reading [of Scripture], to exhorting people and to teaching.
2 Timothy 4:2
Preach the [Gospel] message; be prepared [to do it both] when it is convenient and when it is inconvenient; reprove [i.e., convince people of their wrongdoing], rebuke [i.e., convict people of their sin], and exhort [i.e., urge people to act], with great patience and teaching.
