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... read more
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 ). read more
All the Egyptians digged . Not the Hebrews. The water stored in the houses of the Hebrews in reservoirs, cisterns, and the like, was (it would seem) not vitiated; and this would suffice for the consumption of seven days. Water to drink . Blood would not become water by percolation through earth, as Canon Cook appears to think; but there might have been sufficient water in the ground before the plague began, to fill the wells dug, for seven days. read more
God allows men to seek and obtain alleviations of his judgments. We are not intended to sit down under the judgments of God, and fold our hands, and do nothing. Whether it be war, or pestilence, or famine, or any other Heaven-sent calamity that comes upon us for our sins and those of our nation, we must beware of sinking into apathy under the infliction, and allowing it simply to run its course. God does not desire that we should show our submission in this way. He gives us thought, and... read more
And seven days were fulfilled . This note of time has been regarded as merely fixing the interval between the first plague and the second. But it is more natural to regard it as marking the duration of the first plague. The intervals between one plague and another are nowhere estimated. read more
Turned to blood - This miracle would bear a certain resemblance to natural phenomena, and therefore be one which Pharaoh might see with amazement and dismay, yet without complete conviction. It is well known that before the rise the water of the Nile is green and unfit to drink. About the 25th of June it becomes clear, and then yellow, and gradually reddish like ochre; an effect due to the presence of microscopic cryptogams and infusoria. The supernatural character of the visitation was tested... read more
Shall lothe - The water of the Nile has always been regarded by the Egyptians as a blessing unique to their land. It is the only pure and wholesome water in their country, since the water in wells and cisterns is unwholesome, while rain water seldom falls, and fountains are extremely rare. read more
The Pulpit Commentary - Exodus 7:22
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... read more
