David seems to have been the first king who established a force of chariots, and this he evidently did for the purpose of action on the flat grounds of Palestine, where infantry were at a great disadvantage when attacked by the dreaded chariots; yet he did not controvert the law by multiplying to himself Horses, or even by importing them from Egypt; and when he had an opportunity of adding to his army an enormous force of chariots, he only employed as many as he thought were sufficient for his purpose. After he defeated Hadadezer, and had taken from him a thousand chariots with their Horses together with seven hundred cavalry, he houghed all the Horses except those which were needed for one hundred chariots.
Solomon, however, was more lax, and systematically broke the ancient law by multiplying Horses exceedingly, and sending to Egypt for them. We learn from 1 Kings iv. 26 of the enormous establishment which he kept up both for chariots and cavalry. Besides those which were given to him as tribute, he purchased both chariots and their Horses from Egypt and Syria, the chariots being delivered at the rate of six hundred shekels of silver, and the Horses for an hundred and fifty shekels.
Chariots were far more valued in battle than horsemen, probably because their weight made their onset irresistible against infantry, who had no better weapons than bows and spears. The slingers themselves could make little impression on the chariots; and even if the driver, or the warrior who fought in the chariot, or his attendant, happened to be killed, the weighty machine, with its two Horses, still went on its destructive way.
Of their use in battle we find very early mention. For example, in Exod. xiv. 6 it is mentioned that Pharaoh made ready his chariot to pursue the Israelites; and in a subsequent part of the same chapter we find that six hundred of the Egyptian chariot force accompanied their master in the pursuit, and that the whole army was delayed because the loss of the chariot wheels made them drive heavily.
Then in the familiar story of Sisera and Jael the vanquished general is mentioned as alighting from his chariot, in which he would be conspicuous, and taking flight on foot; and, after his death, his mother is represented as awaiting his arrival, and saying to the women of the household, "Why is his chariot so long in coming? Why tarry the wheels of his chariot?"
During the war of conquest which Joshua led, the chariot plays a somewhat important part. As long as the war was carried on in the rugged mountainous parts of the land, no mention of the chariot is made; but when the battles had to be fought on level ground, the enemy brought the dreaded chariots to bear upon the Israelites. In spite of these adjuncts, Joshua won the battles, and, unlike David, destroyed the whole of the Horses and burned the chariots.
Many years afterwards, a still more dreadful weapon, the iron chariot, was used against the Israelites by Jabin. This new instrument of war seems to have cowed the people completely; for we find that by means of his nine hundred chariots of iron Jabin "mightily oppressed the children of Israel" for twenty years. It has been well suggested that the possession of the war chariot gave rise to the saying of Benhadad's councillors, that the gods of Israel were gods of the hills, and so their army had been defeated; but that if the battle were fought in the plain, where the chariots and Horses could act, they would be victorious.
So dreaded were these weapons, even by those who were familiar with them and were accustomed to use them, that when the Syrians had besieged Samaria, and had nearly reduced it by starvation, the fancied sound of a host of chariots and Horses that they heard in the night caused them all to flee and evacuate the camp, leaving their booty and all their property in the hands of the Israelites.
Whether the Jews ever employed the terrible scythe chariots is not quite certain, though it is probable that they may have done so; and this conjecture is strengthened by the fact that they were employed against the Jews by Antiochus, who had "footmen an hundred and ten thousand, and horsemen five thousand and three hundred, and elephants two and twenty, and three hundred chariots armed with hooks" (2 Macc. xiii. 2). Some commentators think that by the iron chariots mentioned above were signified ordinary chariots armed with iron scythes projecting from the sides.
By degrees the chariot came to be one of the recognised forces in war, and we find it mentioned throughout the books of the Scriptures, not only in its literal sense, but as a metaphor which every one could understand. In the Psalms, for example, are several allusions to the war-chariot. "He maketh wars to cease unto the end of the earth; He breaketh the bow, and cutteth the spear in sunder; He burneth the chariot in the fire" (Ps. xlvi. 9). Again: "At Thy rebuke, O God of Jacob, both the chariot and horse are cast into a dead sleep" (Ps. lxxvi. 6). And: "Some trust in chariots, and some in horses: but we will remember the name of the Lord our God" (Ps. xx. 7). Now, the force of these passages cannot be properly appreciated unless we realize to ourselves the dread in which the war-chariot was held by the foot-soldiers. Even cavalry were much feared; but the chariots were objects of almost superstitious fear, and the rushing sound of their wheels, the noise of the Horses' hoofs, and the shaking of the ground as the "prancing horses and jumping chariots" (Nab. iii. 2) thundered along, are repeatedly mentioned.
