EXPOSITION
On the occurrence of the second sign and first plague, the magicians were again consulted; and, by means which it is impossible to do more the. conjecture, they produced a seeming transformation into blood of a certain quantity of water. The inquiry, whence they procured the water, is answered by Exodus 7:24. That they actually turned water into blood is scarcely asserted in the vague "did so" of Exodus 7:22. Perhaps they had recourse to sleight of hand, and made a substitution, like modem conjurors; perhaps they merely turned the water of a red colour. All that was necessary was to convince Pharaoh that they were able to do what Moses and Aaron had done—there was no one to watch, and test, and examine their pretended miracle, which consequently passed muster, though it may have been no more than a trick. Pharaoh, however, suffered himself to be convinced, and "turned and went into his house" without paying any attention to the marvel wrought (Exodus 7:23).
The magicians of Egypt did so. They could not do what Moses and Aaron had done—stretch out, that is, a rod over the Nile, and turn it and all its branches, and ponds, and pools, into blood, for this was already done. They could only show their skill upon some small quantity of water in a cup or other vessel. No doubt they produced some apparent change, which was accepted by Pharaoh as an equivalent to what had been effected by the Israelite chiefs, but which must have fallen far short of it. Pharaoh would not be a severe critic.
Pharaoh turned—i.e. "returned"—quitted the river-hank, satisfied with what the magicians had done, and went back to the palace. Neither did he set his heart to this also. A better translation is that of Booth-royd—"Nor did he lay even this to heart." In the expression "even this" there is an allusion to the previous neglect of the first sign (Exodus 7:13).
HOMILETICS
The power of Satan is with all deceivableness.
Satan himself, and wicked men, his instruments, are especially strong in the power of deception. Satan deceived Eve (1 Timothy 2:14). The lying spirit deceived Ahab (1 Kings 22:22). Rebekah and Jacob together deceived Isaac. Gehazi deceived Naaman. Bad men are clever and plausible, and keensighted, and painstaking, and careful—they lay their plans skilfully, and carry them out boldly, and are usually successful. The magicians had not only their own credit at stake, but also that of the priests, who were in league with them. They would not be very scrupulous what means they used, so that they could persuade the Pharaoh that whatever Moses and Aaron could do, they could do: and they succeeded. The "father of lies" no doubt suggested to them some clever method of seeming to perform the same sort of miracle as the Israelitish leaders had performed—they adopted it, and cheated the eyes of the beholders. When men wished to nip the religion of Christ in the bud, they called its Founder "that deceiver" (Matthew 27:63). Deceit is a device of Satan. In nothing are the powers of light and darkness more contrasted than in the simpleness, the straightforward sincerity that characterises the former, and the crookedness, the tortuousness, the insincerity that goes with the latter. He who is "the Way" and "the Life," is also "the Truth." All who would have fellowship with him must "walk in truth."
