“I would rather be a doorkeeper in the house of the Lord than dwell in the tents of the wicked.” The Hebrew (hyperbolic) idiom here is simply saying that the lowliest job in the courts of heaven (the door keeper) is better than all the luxuries in the tents of wickedness.
An usher is a person who helps ensure a smoothly running church service and who ministers to people in a variety of practical ways. The specific
responsibilities of an usher vary, but their duties usually include greeting
people as they arrive for the service, assisting people with special needs, and receiving the offering.
The Usher serves his church by providing:
Divine Hospitality
Reverence and Order in the Sanctuary
Assistance to Worshipers
Intercessory Prayer
Ushers stand ready to assist anyone in the congregation who might need help, to aid latecomers in finding a seat, and to inform those in the sanctuary of any urgent matters.
