John Calvin on Exodus 30:10-11

10. And Aaron shall make an atonement. We should observe here the correspondence between the two altars; for, as the Israelites were admonished that the sacrifices would not please God, unless all uncleanness were wiped away by pure and holy prayers, so also the altar of incense was purified by the sprinkling of blood, that they might learn that their prayers obtained acceptance through sacrifices. Although this was only done once a year, yet it was daily to be called to mind, in order that they might offer the death of Christ by faith and prayer, “Ut fide et precibus adolerent mortem Christi.” — Lat. “Afin qu’en appliquant a eux la vertu de la mort de Jesus Christ par foy et prieres;” in order that applying to themselves the virtue of the death of Jesus Christ by faith and prayers. — Fr. and yet might know that their prayers had no sweet savor, unless in so far as they were sprinkled with the blood of atonement.

Exodus 30:34-38

34. And the LORD said unto Moses, Take unto thee sweet spices, stacte, and onycha, and galbanum; these sweet spices with pure frankincense: of each shall there be a like weight:

34. Et dixit Jehova ad Mosen, Accipe tibi aromata, stacten, et onychen, et galbanum, aromata, et thus purum: ut pondus ponderi respondeat.

35. And thou shalt make it a perfume, a confection after the art of the apothecary, tempered together, pure and holy:

35. Et facies ex eo suffimentum aromaticum, opus aromatarii, mistum, purum et sanctum.

36. And thou shalt beat some of it very small, and put of it before the testimony in the tabernacle of the congregation, where I will meet with thee: it shall be unto you most holy.

36. Et contundes ex eo comminuendo: ponesque ex eo coram testimonio in tabernaculo conventionis, in quo conveniam tecum: sanctitas sanctitatum erit vobis.

37. And as for the perfume which thou shalt make, ye shall not make to yourselves according to the composition thereof: it shall be unto thee holy for the LORD.

37. Suffimentum quod facies secundum compositionem ejus non facietis vobis: sanctitas tibi erit Jehovae.

38. Whosoever shall make like unto that, to smell thereto, shall even be cut off from his people.

38. Quisquis fecerit simile ad adolendum ilhd, excidetur e populis suis.
