Answer: The noble task of an overseer
(elder/shepherd/pastor) is to take care of God's church,
(verse 5).
MORE INFORMATION AND/OR OTHER SCRIPTURE REFERENCES:
"Take care of" is literally "direction of
care towards." It is that kind of care that the
Samaritan man gave to the man who was traveling on the road from
Jerusalem to Jericho, was attacked by robbers, stripped of his
clothing, beaten and left half dead. It is NOT the kind of
"care" that the Levite and priest "offered"
(being none):
Luke 10:30-35: "In reply Jesus
said: 'A man was going down from Jerusalem to Jericho, when
he fell into the hands of robbers. They stripped him of his
clothes, beat him and went away, leaving him half dead. A
priest happened to be going down the same road, and when he saw the
man, he passed by on the other side. So, too, a Levite, when
he came to the place and saw him, passed by on the other
side. But a Samaritan, as he traveled, came where the man
was; and when he saw him, he took pity on him. He went to him
and bandaged his wounds, pouring on oil and wine. Then he put the
man on his own donkey, took him to an inn and TOOK CARE OF
HIM. The next day he took out two silver coins and gave them
to the innkeeper. "LOOK AFTER HIM," he said, "and
when I return, I will reimburse you for any extra expense you may
have."'"
