Genesis 9:3 - Wesley's Explanatory Notes

Every moving thing that liveth shall be meat for you — Hitherto man had been confined to feed only upon the products of the earth, fruits, herbs and roots, and all sorts of corn and milk; so was the first grant, Genesis 1:29. But the flood having perhaps washed away much of the virtue of the earth, and so rendered its fruits less pleasing, and less nourishing, God now enlarged the grant, and allowed man to eat flesh, which perhaps man himself never thought of 'till now. The precepts and provisos of this charter are no less kind and gracious, and instances of God's good — will to man. The Jewish doctors speak so often of the seven precepts of Noah, or of the sons of Noah, which they say were to be observed by all nations, that it may not be amiss to set them down. The first against the worship of idols. The second against blasphemy, and requiring to bless the name of God. The third against murder. The fourth against incest and all uncleanness. The fifth against theft and rapine. The sixth requiring the administration of justice. The seventh against eating flesh with the life. These the Jews required the observation of, from the proselytes of the gate. But the precepts here given, all concern the life of man. Man must not prejudice his own life by eating that food which is unwholsome, and prejudicial to his health.
