Adam Clarke Bible Commentary

Rise, Peter, kill and eat - Θυσον και φαγε, Sacrifice and eat. Though this verb is sometimes used to signify the slaying of animals for food, yet, as the proper notion is to slay for the purpose of sacrifice, it appears to me to be better to preserve that meaning here. Animals that were offered in sacrifice were considered as given to God; and, when he received the life, the flesh was given to those who offered the sacrifice, that they might feed upon it; and every sacrifice had in it the nature of a covenant; and covenants were usually made by eating together on the flesh of the sacrifice offered on the occasion, God being supposed to be invisibly present with them, and partaking of the feast. The Jews and Gentiles are certainly represented by the clean and unclean animals in this large vessel: these, by the ministry of the Gospel, were to be offered up a spiritual sacrifice to God. Peter was to be a prime instrument in this work; he was to offer them to God, and rejoice in the work of his hands. The spirit of the heavenly direction seems to be this: "The middle wall of partition is now to be pulled down; the Jews and Gentiles are called to become one flock, under one shepherd and bishop of souls. Thou, Peter, shalt open the door of faith to the Gentiles, and be also the minister of the circumcision. Rise up; already a blessed sacrifice is prepared: go and offer it to God; and let thy soul feed on the fruits of his mercy and goodness, in thus showing his gracious design of saving both Jews and Gentiles by Christ crucified."
