John Calvin on Numbers 8:24-26

24. This is it, that belongeth to the Levites. The age is here prescribed when the Levites should begin and end the execution of their office. God commands them to commence in their 25th year and grants them their dismissal in their 50th; and for both these provisions there is very good reason. For, if they had been admitted in early youth, their levity might have greatly detracted from the reverence due to sacred things: not only because those, whose manhood is not yet mature, are generally given to pleasure and intemperance, but because either by negligence, or levity, or want of thought, or ignorance and error, they might have made many grievous mistakes in the service of God; and, whilst they were by no means fitted to exercise their charge until they should have attained prudence and gravity, so also, lest they should fail from old age, it was right that they should be seasonably dismissed; for as we have before said, their duties were laborious, and such as demanded bodily strength. If, however, any should choose to make an application of this to the pastoral office, it should be generally remembered, that none should be chosen to it except such as have already given proofs of their moderation, and float those who diligently devote themselves to it should not be unreasonably pressed upon, nor should more be required of them than their ability can bear; for some foolishly count their years, as if it were a sin to choose a pastor before his 24th year, although he might be otherwise fully provided with the necessary qualifications.

Numbers 3

Numbers 3:5-10

5. And the LORD spake unto Moses, saying,

5. Loquutus est autem Jehova ad Mosen, dicendo:

6. Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him.

6. Appropinquare fac tribum Levi, et siste eam coram Aharone sacerdote, ut ministret ei.

7. And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle.

7. Et custodiant custodiam ejus, et custodiam universi coatus coram tabernaculo conventionis, ut exequantur cultum tabernaculi.

8. And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle.

8. Custodiant quoque omnia utensilia tabernaculi conventionis, custodiamque filiorum Israel, ut exequantur culture tabernaculi.

9. And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.

9. Da inquam Levitas ipsi Aharon, et filiis ejus: dati, dati namque sunt illi ex filiis Israel.

10. And thou shalt appoint Aaron and his sons, and they shall wait on their priest’s office: and the stranger that cometh nigh shall be put to death.

10. Aharon autem et filios ejus praeficies, custodientque sacerdotium suum: externus sane qui accesserit morietur.
