Parallel
Numbers 4:27
Jewish Publication Society 1917 · Berean Standard Bible
At the commandment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burden, and in all their service; and ye shall appoint unto them in charge all their burden.
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.
