To abstain from fornication — Which even the philosophers among the heathens did not account any fault. It was particularly frequent in the worship of their idols, on which account they are here named together. And from things strangled — That is, from whatever had been killed, without pouring out the blood. When God first permitted man to eat flesh, he commanded Noah, and in him all his posterity, whenever they killed any creature for food, to abstain from the blood thereof. It was to be poured upon the ground as water: doubtless in honour of that blood which was in due time poured out for the sin of the world.
