257. "Over Philistia I will cry in triumph" (Tehilim 108:10). This too, David saw with distant vision. He said, Canaan is the bad side of the Other Side and the Philistines stem from there, FROM CANAAN (YEHOSHUA 13). What is there TO BE DONE against the Other Side? It is the blowing of the horn (Heb. truah), as it says, "if you go to war in your land...then you shall blow an alarm..." (Bemidbar 10:9). TRUAH MEANS BREAKING in order to break down his power and strength. Therefore, "over Philistia I will cry (blow) in triumph," MEANING HE WILL BREAK THEM, because that is what they deserve.
