In the third chapter we have an account of the whole number of the Levites; and here of those only who were able to serve the Lord in the sanctuary. By comparing the two places, we find the number of the effective and ineffective males. Thus we find that the whole number of the Levites amounted to 22,300; of whom 8,580 were fit for service and 13,720 unfit, being either too old or too young. What an astonishing number of men, all performing some service by which God was glorified, and the congregation at large benefited!
