xvii. 8-16.
Nothing can be more natural, to those who remember the value of a fountain in the East, than that Amalek should swoop down from his own territories upon Israel, as soon as this abundant river tempted his cupidity. This unprovoked attack of a kindred nation leads to another advance in the education of the people.
They had hitherto been the sheep of God: now they must become His warriors. At the Red Sea it was said to them, "Stand still, and see the salvation of the Lord ... the Lord shall fight for you, and ye shall hold your peace" (xiv. 13). But it is not so now. Just as the function of every true miracle is to lead to a state of faith in which miracles are not required; just as a mother reaches her hand to a tottering infant, that presently the boy may go alone, so the Lord fought for Israel, that Israel might learn to fight for the Lord. The herd of slaves who came out of Egypt could not be trusted to stand fast in battle; and what a defeat would have done with them we may judge by their outcries at the very sight of Pharaoh. But now they had experience of Divine succour, and had drawn the inspiring breath of freedom. And so it was reasonable to expect that some chosen men of them at least will be able to endure the shock of battle. And if so, it was a matter of the last importance to develop and render conscious the national spirit, a spirit so noble in its unselfish readiness to die, and in its scorn of such material ills as anguish and mutilation compared with baseness and dishonour, that the re-kindling of it in seasons of peril and conflict is more than half a compensation for the horrors of a battle-field.
We do not now inquire what causes avail to justify the infliction and endurance of those horrors. Probably they will vary from age to age; and as the ties grow strong which bind mankind together, the rupture of them will be regarded with an ever-deepening shudder,--just as England to-day would certainly refuse to make war upon our American kinsmen for a provocation which (rightly or wrongly) she would not endure from Russians. But the point to be observed is that war cannot be inherently immoral, since God instructed in war the first nation that He ever trained, not using its experience of His immediate interpositions to supersede all need of human strife, but to make valiant soldiers, and adding some of the most precious lessons of all their later experience on the battle-field and by the sword. Now, it assuredly cannot be shown that anything in itself immoral is fostered and encouraged by the Old Testament. Slavery and divorce, which it was not yet possible to extirpate, were hampered, restricted, and reduced to a minimum, being "suffered" "because of the hardness of 'their' hearts" (Matt. xix. 8). The wildest assailant of the Pentateuch will scarcely pretend that it fosters and incites either divorce or slavery, as, beyond all question, it encourages the martial ardour of the Jews.
And yet war, though permissible, and in certain circumstances necessary, is only necessary as the lesser of two evils; it is not in itself good. Solomon, not David, could build the temple of the Lord; and Isaiah sharply contrasts the Messiah with even that providentially appointed conqueror, the only pagan who is called by God "My anointed," in that the one comes upon rulers as upon mortar, and as the potter treadeth clay, but the Other breaks not a bruised reed, nor quenches the smoking flax (Isa. xli. 25, xlii. 3, xlv. 1). The ideal of humanity is peace, and also it is happiness, but war may not yet have ceased to be a necessity of life, sometimes as ruinous to evade as any other form of suffering.
