"Stand, O L-rd, and let Your foes be scattered": "Your foes": those who are massed to attack us. "and let Your haters (those in pursuit) flee before You." They will flee, and we will not be destroyed by them. ("before You" [lit., "before Your face"]) When Your face is with us, we will not flee before them, and if not, we will fall before them. And thus is it written (Shemot 33:15) "If Your 'face' does not go, do not bring us up from here," and (Ibid. 16) "For how, otherwise, will it be known that I and Your people have found favor in Your eyes," and (Joshua 10:11) "And it was, when they fled before Israel, they were on the descent of Beth Choron, when the L-rd cast upon them great stones, etc.", and (Psalms 83:115) "My G-d, make them like whirling chaff, like stubble before the wind, like a fire burning mountains."
