biblical text. Kurtz is of opinion that they took spring water for the purpose; but he has overlooked the fact, that if spring water was still to be had, there would be no necessity for the Egyptians to dig wells for the purpose of finding drinkable water. The supposition that the magicians did not try their arts till the miracle wrought by Aaron had passed away, is hardly reconcilable with the text, which places the return of Pharaoh to his house after the work of the magicians. For it can neither be assumed, that the miracle wrought by the messengers of Jehovah lasted only a few hours, so that Pharaoh was able to wait by the Nile till it was over, since in that case the Egyptians would not have thought it necessary to dig wells; nor can it be regarded as probable, that after the miracle was over, and the plague had ceased, the magicians began to imitate it for the purpose of showing the king that they could do the same, and that it was after this that the king went to his house without paying any need to the miracle. We must therefore follow the analogy of Exo 9:25 as compared with Exo 10:5, and not press the expression, “every collection of water” (Exo 7:19), so as to infer that there was no Nile water at all, not even what had been taken away before the smiting of the river, that was not changed, but rather conclude that the magicians tried their arts upon water that was already drawn, for the purpose of neutralizing the effect of the plague as soon as it had been produced. The fact that the clause, “Pharaoh's heart was hardened,” is linked with the previous clause, “the magicians did so, etc.,” by a vav consecutive, unquestionably implies that the imitation of the miracle by the magicians contributed to the hardening of Pharaoh's heart. The expression, “to this also,” in Exo 7:23, points back to the first miraculous sign in Exo 7:10. This plague was keenly felt by the Egyptians; for the Nile contains the only good drinking water, and its excellence is unanimously attested by both ancient and modern writers (Hengstenberg ut sup. pp. 108, 109, transl.). As they could not drink of the water of the river from their loathing at its stench (Exo 7:18), they were obliged to dig round about the river for water to drink (Exo 7:24). From this it is evident that the plague lasted a considerable time; according to Exo 7:25, apparently seven days. At least this is the most natural interpretation of the words, “and seven days were fulfilled after that Jehovah had smitten the river.”
