Parallel
Numbers 4:27
Brenton's English Septuagint · Berean Standard Bible
According to the direction of Aaron and his sons shall be the ministry of the sons of Gedson, in all their ministries, and in all their works; and thou shalt take account of them by name in all things borne by them.
All the service of the Gershonites—all their transport duties and other work—is to be done at the direction of Aaron and his sons; you are to assign to them all that they are responsible to carry.
