Numbers 4:33

This is the service of the families of the sons of Merari, according to all their service, in the Tabernacle of the Congregation, under the hand of Ithamar, the son of Aaron, the priest, who was superintendent of this part of the work. The work of the Gospel ministry is also a good work, 1 Timothy 3:1, and those that are engaged in preaching should comport themselves as good soldiers of Jesus Christ, in the spiritual warfare against the enemies of their faith, 1 Timothy 1:18; Ephesians 6:10.
