John Calvin on Deuteronomy 12:23-25

23. Only be Lat., “Roberare.” Margin, A. V., “Heb., Be strong.” sure that thou eat not. It is not without cause that he earnestly exhorts them to inflexible firmness, because it was both a matter trifling in appearance, and its observation troublesome, whilst it was easy to decline from it on account of the universal example of the Gentiles. For if they considered within themselves that it contributed not to holiness that they should not touch blood, hence a snare to indulgence might easily have arisen.

Leviticus 17

Leviticus 17:10-14

10. And whatsoever man there be of the house of Israel, or of the strangers that sojourn among you, that eateth any manner of blood; I will even set my face against that soul that eateth blood, and will cut him off from among his people.

10. Quicunque e domo Israel, et e peregrinis qui peregrinantur in medio eorum, comederit ullum sanguinem, ponam faciem meam in animam quae comederit sanguinem, et excidam eam e medio populi sui.

11. For the life of the flesh is in the blood; and I have given it to you upon the altar, to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.

11. Quia anima carnis in sanguine est: ego autem dedi illum vobis super altare ad expiandum animus vestras, quia sanguis animam expiabit.

12. Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood.

12. Ideo dixi filiis Israel, Nulla anima ex vobis comedet sanguinem, et peregrinus qui pregrinatur in medio vestri non comedet sanguinem.

13. And whatsoever man there be of the children of Israel, or of the strangers that sojourn among you, which hunteth and catcheth any beast or fowl that may be eaten; he shall even pour out the blood thereof, and cover it with dust.

13. Et quicunque e filiis Israel, et e peregrinis qui peregrinantur in medio eorum, venatus fuerit venationem bestiae vel avis quae comeditur, effundet sanguinem ejus et cooperiet pulvere.

14. For it is the life of all flesh; the blood of it is for the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh: for the life of all flesh is the blood thereof; whosoever eateth it shall be cut off.

14. Quia anima cujusque carnis, sanguis ejus est in anima: dixique filiis Israel, Sanguinem cujuscunque carnis non comedetis, quia anima cujusque carnis est sanguis ejus: quicunque comederit illum, excidetur.
