John Calvin on Numbers 10:10

10. Also in the day of your gladness. This was as if God should make it manifest that He approved of no festivals, and that no sacrifices pleased Him, except His command should go before them; for it was not lawful for the people to choose this or that day, but the authority for prescribing them was in the hands of the ministers of sacred things. And, indeed, God Himself had appointed the New-moons (Neomenias, vel novilunia) and the other solemnities; but, lest any change should occur, since men are ever daring in their innovations, He would have their lawful observation sanctioned by the sound of the trumpets; as if, by the mouth of the priests, He Himself published the holy assemblies. The sacrifices, which others have translated “of your peace-offerings,” So A.V שלמיכם, Pacificorum vestrorum, is the rendering of SM. To justify rendering this form of the word your prosperities, the vowel-points should be different. Your sacrifices of thanksgiving, is the ordinary interpretation of the lexicographers. — W I translate, and not without reason, “of your prosperities.” For this is what שלמיכם, shalmecem, properly means; and it was the name they gave to their supplications and testimonies of thanksgiving, when they had been delivered from some great danger, or were visited by some extraordinary blessing from God. But Moses says that the trumpets were to be “for a memorial before their God;” because when they should have assembled at His command, He would look upon them, and honor them with His paternal favor.

The Second Commandment

Exodus 20

Exodus 20:4-6

4. Thou shalt not make unto thee any graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:

4. Non facies tibi sculptlie, neque ullam imaginem eorum quae sunt in coelo sursum, neque eorum qae in terra deorsum, neque eorum quae in aquis sunt subter terram.

5. Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;

5. Non adorabis ea, neque coles ea, ego enim Jehova Deus tuus, Deus zelotes, visitans iniquitatem patrum super filios, in tertiam et quartam generationem in his qui me oderunt:

6. And shewing mercy unto thousands of them that love me, and keep my commandments.

6. Et faciens misericordiam: in mille diligentibus me, et custodientibus praecepta mea.
