According to the commandment of the LORD they were numbered by the hand of Moses, every one according to his service, and according to his burden: thus were they numbered of him, as the LORD commanded Moses.
According to the commandment of the LORD through Moses they were listed, each one with his task of serving or carrying. Thus they were listed by him, as the LORD commanded Moses.
When their names were recorded, as the LORD had commanded through Moses, each man was assigned his task and told what to carry. And so the registration was completed, just as the LORD had commanded Moses.
