When Moses received his commission, at the bush, words were spoken which are now repeated with more emphasis, and which have to be considered carefully. For probably no statement of Scripture has excited fiercer criticism, more exultation of enemies and perplexity of friends, than that the Lord said, “I will harden Pharaoh’s heart, and he shall not let the people go,” and that in consequence of this Divine act Pharaoh sinned and suffered. Just because the words are startling, it is unjust to quote them without careful examination of the context, both in the prediction and the fulfilment. When all is weighed, compared, and harmonised, it will at last be possible to draw a just conclusion. And although it may happen long before then, that the objector will charge us with special pleading, yet he will be the special pleader himself, if he seeks to hurry us, by prejudice or passion, to give a verdict which is based upon less than all the evidence, patiently weighed.
Let us in the first place find out how soon this dreadful process began; when was it that God fulfilled His threat, and hardened, in any sense whatever, the heart of Pharaoh? Did He step in at the beginning, and render the unhappy king incapable of weighing the remonstrances which He then performed the cruel mockery of addressing to him? Were these as insincere and futile as if one bade the avalanche to pause which his own act had started down the icy slopes? Was Pharaoh as little responsible for his pursuit of Israel as his horses were—being, like them, the blind agents of a superior force? We do not find it so. In the fifth chapter, when a demand is made, without any sustaining miracle, simply appealing to the conscience of the ruler, there is no mention of any such process, despite the insults with which Pharaoh then assails both the messengers and Jehovah Himself, Whom he knows not. In the seventh chapter there is clear evidence that the process is yet unaccomplished; for, speaking of an act still future, it declares, “I will harden Pharaoh’s heart, and multiply My signs and My wonders in the land of Egypt” (vii. 3). And this terrible act is not connected with the remonstrances and warnings of God, but entirely with the increasing pressure of the miracles.
