Jerusalem having been acquired, David had to prepare for war with the Philistines, in which the king gave proof at once of his heroic courage and his unshakable trust in God. The latter quality he displayed signally in the battle that took place in the Valley of the Giants. God had commanded David not to attack the host of the Philistines until he heard "the sound of marching in the tops of the mulberry trees." God desired to pass judgment upon the tutelary angels of the heathen, before surrendering the heathen themselves to the pious, (54) and the motion of the tops of the trees was to indicate that the battle could proceed. The enemy advanced until there were but four ells between them and the Israelites. The latter were about to throw themselves against the Philistines, but David restrained them, saying: "God forbade me to attack the Philistines before the tops of the trees begin to move. If we transgress God's command, we shall certainly die. If we delay, it is probable that we shall be killed by the Philistines, but, at least, we shall die as pious men that keep God's command. Above all, let us have confidence in God." Scarcely had he ended his speech when the tops of the trees rustled, and David made a successful assault upon the Philistines. Whereupon God said to the angels, who were constantly questioning him as to why he had taken the royal dignity from Saul and given it to David: "See the difference between Saul and David." (55)
Of David's other campaigns, the most notable is his war with Shobach the Aramean, whom he conquered in spite of his gigantic size and strength. Shobach was very tall, as tall as a dove-cote, and one look at him sufficed to strike terror to the heart of the beholder. (56) The Aramean general indulged in the belief that David would treat the Syrians gently on account of the monument, still in existence at that time, which Jacob and Laban had erected on the frontier between Palestine and Aram as a sign of their covenant that neither they nor their descendants should wage war with each other. But David destroyed the monument. (57) Similarly, the Philistines had placed trust in a relic from Isaac, the bridle of a mule which the Patriarch had given to Abimelech, the king of the Philistines, as a pledge of the covenant between Israel and his people. David took it from them by force. (58)
However, David was as just as he was bold. Disregard of the covenants made by the Patriarchs was far removed from his thoughts. Indeed, before departing for the wars with the Arameans and the Philistines, he had charged the Sanhedrin to investigate carefully the claims of the two nations. The claims of the Philistines were shown to be utterly unfounded. In no sense were they the descendants of those Philistines who had concluded a treaty with Isaac; they had immigrated from Cyprus at a much later date. The Arameans, on the other hand, had forfeited their claims upon considerate treatment, because under the "Aramean" Balaam, and later again, in the time of Othniel, under their king Cushan-rishathaim, they had attacked and made war upon the Israelites. (59)
AHITHOPHEL
Among David's courtiers and attendants, a prominent place is occupied by his counsellor Ahithophel, (60) with whom the king was connected by family ties, Bath-sheba being his granddaughter. (61) Ahithophel's wisdom was supernatural, for his counsels always coincided with the oracles rendered by the Urim and Thummim, and great as was his wisdom, it was equalled by his scholarship. Therefore David did not hesitate to submit himself to his instruction, (62) even though Ahithophel was a very young man, at the time of his death not more than thirty-three years old. (63) The one thing lacking in him was sincere piety, (64) and this it was that proved his undoing in the end, for it induced him to take part in Absalom's rebellion against David. Thus he forfeited even his share in the world to come. (65)
To this dire course of action he was misled by astrologic and other signs, which he interpreted as prophecies of his own kingship, when in reality they pointed to the royal destiny of his granddaughter Bath-sheba. (66) Possessed by his erroneous belief, he cunningly urged Absalom to commit an unheard-of crime. Thus Absalom would profit nothing by his rebellion, for, though he accomplished his father's ruin, he would yet be held to account and condemned to death for his violation of family purity, and the way to the throne would be clear for Ahithophel, the great sage in Israel. (67)
The relation between David and Ahithophel had been somewhat strained even before Absalom's rebellion. Ahithophel's feelings had been hurt by his being passed over at the time when David, shortly after ascending the throne, invested, on a single day, no less than ninety thousand functionaries with positions.
On that day a remarkable incident occurred. When the Ark was to be brought up from Geba to Jerusalem, the priests who attempted to take hold of it were raised up in the air and thrown violently to the ground. In his despair the king turned for advice to Ahithophel, who retorted mockingly: "Ask thy wise men whom thou hast but now installed in office." It was only when David uttered a curse on him who knows a remedy and withholds it from the sufferer, that Ahithophel advised that a sacrifice should be offered at every step taken by the priests. Although the measure proved efficacious, and no further disaster occurred in connection with the Ark, yet Ahithophel's words had been insincere. He knew the real reason of the misadventure, and concealed it from the king. Instead of following the law of having the Ark carried on the shoulders of priests, David had had it put on a wagon, and so incurred the wrath of God. (68)
Ahithophel's hostility toward David showed itself also on the following occasion. When David was digging the foundations of the Temple, a shard was found at a depth of fifteen hundred cubits. David was about to lift it, when the shard exclaimed: "Thou canst not do it." "Why not?" asked David. "Because I rest upon the abyss." "Since when?" "Since the hour in which the voice of God was heard to utter the words from Sinai, 'I am the Lord thy God,' causing the earth to quake and sink into the abyss. I lie here to cover up the abyss." Nevertheless David lifted the shard, and the waters of the abyss rose and threatened to flood the earth. Ahithophel was standing by, and he thought to himself: "Now David will meet with his death, and I shall be king." Just then David said: "Whoever knows how to stem the tide of waters, and fails to do it, will one day throttle himself." (69) Thereupon Ahithophel had the Name of God inscribed upon the shard, and the shard thrown into the abyss. The waters at once commenced to subside, but they sank to so great a depth that David feared the earth might lose her moisture, and he began to sing the fifteen "Songs of Ascents," to bring the waters up again. (70)
Nevertheless David's curse was realized. Ahithophel ended his days by hanging himself. His last will contained the following three rules of conduct: (71) 1. Refrain from doing aught against a favorite of fortune. 2. Take heed not to rise up against the royal house of David. 3. If the Feast of Pentecost falls on a sunny day, then sow wheat. (72)
