HARMONY OF THE LAW · VOLUME 1 the promise. Therefore he relieves his confidence from the imputation of rashness, since he advanced nothing which he had not already heard from the mouth of God himself. These words, "Wherefore criest thou unto me?" some interpreters extend to the whole people, whose representative Moses was; but this sense is too far-fetched, and I have recently observed, that the prayers of the people were by no means directed to God. I doubt not., therefore, that the holy man had prayed apart in the insurrection of the people. Nor is this pious duty disapproved of in the passage; but rather shows that he had not spent his labor in vain, nor poured forth his words into the air. The sense, then, is, "Weary not yourself by crying any more; the event will prove that you are heard. Lift up your rod, then, whereby you may divide the sea, so that the children of Israel may go dry shod through the midst of it." This passage shows that they are guilty of rashness who promise anything either to themselves or others, as to particular blessings, without the special testimony of God.
17. I will harden. God once more affirms, for the greater exaltation of His own power, that He will harden the Egyptians, so that, as if devoted to destruction, they may cast themselves into the midst of the sea; which they certainly would never have done, unless He had guided their hearts by his secret influence; because it could not have escaped them that a passage for the Israelites was opened by His special gift, from whence they might gather that the elements were at war with them. Therefore they would never have dared to enter the sea, which they saw to be armed against them, unless they had been blinded by God. Whence it appears how unworthy is the imagination of those who pretend that there was but a bare permission here, where God would make His power conspicuous. It would have been enough that after the Israelites had passed over to the opposite shore the sea should have returned to its place and prevented the Egyptians from following; but God was willing, by a double miracle, to consult for the security of His people for a long' time to come. And this, indeed, came to pass; for the flower of the whole nation being destroyed, the Egyptians were unable to recruit their army; especially when the heir to the throne had already been slain, and the king himself was now taken away. On this account it is said, that the Egyptians should know that the God of Israel was the Lord; because in this last act they found that the power of rebellion was altogether taken from them.
