New Defender's Study Bible Notes
7:15 shall be eaten. The only offering of which a portion could be eaten by the one making the offering was the peace offering (Leviticus 22:29,30), also called the thanks offering.
7:24 in no wise eat. The disposal of dead animals in this situation would seem like a waste of potential food needed by the Israelite multitudes, but was nevertheless a hygienic measure understood by Moses (possibly by revelation), even though such practices were not followed by other nations.
7:26 eat no manner of blood. The prohibition against eating blood began with the Noahic covenant (Genesis 9:4), and continues today (note Acts 15:20,29). The blood both contains and symbolizes life (Leviticus 17:10-13), and thus should not be eaten. Furthermore, modern medical science confirms that blood tends to become septic soon after death, and hence is dangerous to health.
