First remove the plank from your own eye.
Some people make judging others their specialty.
They each had a special responsibility during the Sunday sermons. The duty of Pointer was to call out the names of those in the congregation who needed to take particular note of the sermon. Jesus warned about the danger of pointing out the faults of others. He said people with planks in their eyes should not attempt to remove specks out of other people's eyes. He challenged His hearers to choose humility rather than hypocrisy by always applying the truth to themselves before noting the faults in others.
