חִצֵּ֣י גִבּ֣וֹר שְׁנוּנִ֑ים עִ֝֗ם גַּחֲלֵ֥י רְתָמִֽים׃
就是勇士銳利的箭，加上羅騰木的炭火。
Rashi
Sharpened arrows of a mighty man Behold you kill in a distant place like an arrow.
Metzudat David
1. You are like sharp arrows in the warrior's hands, because he kills with them from a distance. So too you, who are speaking lashon hara and you will kill the one who is standing at a distance.
Rashi
with coals of brooms All coals, when extinguished on the outside, are extinguished on the inside, but these extinguish themselves on the outside but not on the inside (ibid.). Another explanation: What will He give you? What is the Holy One, blessed be He, destined to decree upon you? Arrows of a mighty man with coals of brooms. His arrows from above and Gehinnom from below.
