In the last verse, there was only a hint of the rescue, and now more detail is given of that incident saying: ``Remember you, when We divided the sea for you, and saved you, and drowned Pharaoh's people within your sight.The event of PASS-OVER and RESCUE has been mentioned through many verses in different chapters of QURÄN, such as: S 7: 136 - S 8:103 - S 63,66 - s 42:55 and s 44: 17'' In these chapters, the event that; the Israelites escaped from Egypt, and were pursued by Pharoah and his host, and then by a miracle, the sea parted, and Israelties crossed it, but Pharaoh and his host were drowned; is mentioned with different aspects and specifications. But in this verse here (NO. 50) it is merely refered to as a favour of Allah to the Israelties, in order to encourage them to believe in the new revelations. It also may teach a lesson to MAN, that if he relies upon God and has confidence in HIM; He will help man in his most dangerous and critical conditions and affairs.
