1137 Cf. 2:65 and n. 79. Fishing, like every other activity, was prohibited to Israel on the Sabbath day. As this practice was usually observed, the fish used to corne up with a sense of security to their water channels or pools openly on the Sabbath day, but not on other days when fishing was open. This was a great temptation to the law-breakers, which they could not resist. Some of their men of piety protested, but it had no effect. When their transgressions, which, we may suppose, extended to other commandments, passed beyond bounds, the punishment came. (R).
21 The people of Aylah, an ancient town by the Red Sea, were forbidden to catch fish on the Sabbath. However, on Saturdays fish were everywhere, whereas on weekdays no fish were seen. To get around the prohibition, some decided to lay their nets on Fridays and collect the fish caught in their nets on Sundays. Those opposed to this practice were divided into two groups: one group tried to convince the offenders to honour the Sabbath, but soon gave up when their advice was not taken seriously. The second group was persistent in giving advice to the Sabbath-breakers. Eventually, the Sabbath-breakers were punished whereas the other two groups were saved.
