We can see here, too, a frequent characteristic of the miraculous element in Scripture, namely, its reaching its end not by a leap, but by a process. Once admit miracle, and it appears as if adaptation of means to ends was unnecessary. It would have been as easy to have transported the Israelites bodily and instantaneously to the other side of the sea, as to have taken these precautions and then cleft the ocean, and made them march through it. Legendary miracle would have preferred the former way. The Bible miracle usually adapts methods to aims, and is content to travel to its goal step by step.
Nor can we omit to notice the double effect of the one manifestation of the divine presence. The same pillar was light and darkness. The side which was cloud was turned to the pursuers; that which was light, to Israel. The former were paralysed, and hindered from advancing a step, or from seeing what the latter were doing; these, on the other hand, had light thrown on their strange path, and were encouraged and helped to plunge into the mysterious road, by the ruddy gleam which disclosed it. So every revelation is either light or darkness to men, according to the use they make of it. The ark, which slew Philistines, and flung Dagon prone on his own threshold, brought blessing to the house of Obededom. The Child who was to be 'set for the fall,' was also for 'the rising of many.' The stone laid in Zion is 'a sure foundation,' and 'a stone of stumbling.' The Gospel is the savour of life unto life, or of death unto death. The same fire melts wax and hardens clay. The same Christ is salvation and destruction. God is to each of us either our joy or our dread.
II. The sudden march of the Egyptians having thus been arrested, there is leisure, behind the shelter of the fiery barrier, to take the next step in the deliverance. The sea is not divided in a moment. Again, we have a process to note, and that brought about by two things,--Moses' outstretched rod, and the strong wind which blew all night. The chronology of that fateful night is difficult to adjust from our narrative. It would appear, from verse 20, that the Egyptians were barred advancing until morning; and, from verse 21, that the wind which ploughed with its strong ploughshare a furrow through the sea, took all night for its work. But, on the other hand, the Israelites must have been well across, and the Egyptians in the very midst of the passage, 'in the morning watch,' and all was over soon after 'the morning appeared.' Probably the wind continued all the night, so as to keep up the pressure which dammed back the waters, but the path was passable some hours before the gale abated. It must have been a broad way to admit of some two million frightened people with wives and children effecting a crossing in the short hours of part of one night.
But though God used the wind as His besom to sweep a road clear for His people, the effect produced by ordinary means was extraordinary. No wind that ever blew would blow water in two opposite directions at once, as a man might shovel snow to right and left, and heap it in mounds by the sides of the path that he dug. That was what the text tells us was done. The miracle is none the less a miracle because God employed physical agents, just as Christ's miracles were no less miraculous when He anointed blind eyes with moistened clay, or sent men to wash in Siloam, than when His bare word raised the dead or stilled the ocean. Wind or no wind, Moses' rod or no rod, the true explanation of that broad path cleared through the sea is--'the waters saw Thee, O God.' The use of natural means may have been an aid to feeble faith, encouraging it to step down on to the untrodden and slippery road. The employment of Moses and his rod was to attest his commission to act as God's mouthpiece.
