It is not meet so to do. So many animals were held sacred by the Egyptians, some universally, some partially, that, if they held a great festival anywhere in Egypt, the Israelites could not avoid offending the religious feelings of their neighbours.
Some animals would be sure to be sacrificed—white cows, or heifers, for instance—by some of the people, which the Egyptians regarded it as sacrilegious to put to death. A bloody conflict, or even a civil war, might be the consequence.
By the abomination of the Egyptians seems to be meant animals of which the Egyptians would abominate the killing. It has generally been supposed that either cows alone, or "cows, bulls and oxen" are meant; but recent researches seem to show that it was only white cows which it was absolutely unlawful to sacrifice.
Will they not stone us? Death was the legal penalty for wilfully killing any sacred animal in Egypt (Herod. 2.65). On one occasion even a Roman ambassador was put to death for accidentally killing a eat (Diod.
Sic. 1.88). Stoning does not appear to have been a legal punishment in Egypt, so that we must suppose Moses to have feared the people present taking the law into their own hands, seizing the sacrificers, and killing them by this ready method.
