English Standard Version
They minister to their brothers in the tent of meeting by keeping guard, but they shall do no service. Thus shall you do to the Levites in assigning their duties."New International Version
They may assist their brothers in performing their duties at the Tent of Meeting, but they themselves must not do the work. This, then, is how you are to assign the responsibilities of the Levites."Catholic Public Domain Version
And they shall be the ministers of their brothers in the tabernacle of the covenant, in order to care for the things that have been commended to them, but not to perform the works themselves. So shall you assign the Levites in their duties.
