12. And he looked this way and that way. Hence it more evidently appears that Moses came with the design of succouring his unhappy brethren, and of relieving and aiding them with his help, since, by killing the Egyptian, he avenged the injury done indeed to an individual, but having a bearing on the whole nation. But although he was inspired by the Holy Spirit with special courage for the performance of this act, still it was accompanied with an infirmity, which shews that he did not undertake without hesitation what he yet, knew to be his vocation. For Stephen (Acts 7:25) bears witness that Moses was not impelled by a rash zeal to stay the Egyptian, but because he knew that he was divinely appointed to be the avenger and deliverer of his nation. Still he looked about to see whether any one saw him, and dared not punish the wrong-doer, except by a secret blow. Thus we perceive that he was not altogether so bold as he should have been, and that he had to strive against his timidity. Again, we gather from his hesitation that his faith was weak, so that we must not suppose that it was thus praised by the Apostle because it was absolutely perfect. In the first place, then, let us conclude that Moses did not rashly have recourse to the sword, but that he was armed by God’s command, and, conscious of his legitimate vocation, rightly and judiciously assumed that character which God assigned to him. Thence it follows, that private persons would act improperly, and would be by no means countenanced by his example, if they sought to repress wrong by force and arms. Thus far we should imitate Moses in rendering aid to the suffering and oppressed, as far as our means go, and in caring not to incur the ill-will of the wicked, when we oppose ourselves to their oppressions; but we must leave it to the judges, who are invested with public authority, to draw the sword of vengeance. If these do not afford their aid to the innocent when they are unjustly treated, all we can do is to murmur; as not even Moses would have been allowed to proceed further, unless he had been the appointed avenger and deliverer of the people. As to the fear, by which he betrayed his pusillanimity and his present unpreparedness for fulfilling his office, let us learn that the obedience of the saints, which is stained by sin, is still sometimes acceptable with God through mercy; and therefore, although the weakness of the flesh is a draw-back to us in the performance of our duty, still let us cease not to struggle against it; for our assurance of this ought to have no small effect in animating us, when we are persuaded that there is pardon ready for our hesitation, if we do not yield to it.
