אַשְׁרֵ֤י הַגֶּ֗בֶר אֲשֶׁ֤ר מִלֵּ֥א אֶת־אַשְׁפָּת֗וֹ מֵ֫הֶ֥ם לֹֽא־יֵבֹ֑שׁוּ כִּֽי־יְדַבְּר֖וּ אֶת־אוֹיְבִ֣ים בַּשָּֽׁעַר׃
Szczęsny mąż, który napełnił swój kołczan niemi; nie powstydzą się, gdy się rozprawią z nieprzyjacielem w bramie.
Rashi
Your arrows are sharpened, etc., in the heart of the king’s enemies Heb. שְּׁנוּנִים, is aiguises in French, sharpened. This is a transposed verse. We find that the disciples are called arrows, as it is stated (above 127:4): “As arrows in the hand of a mighty man, so are the children of youth.” And Torah scholars who argue with each other about halachah are called enemies to each other for the time, as it is stated: “they will not be ashamed when they speak with the enemies in the gate.”
Tze'enah Ure'enah
The third is that one fears that he will be gossiped about that he is despicably stingy, or a glutton and the landlord will tell everything. However when the Holy One is the landlord, he does not disclose anything about what the person does. As we find that a wise person says to his friend: he belittled him and said bad things to people about this wise person. The wise person responded that we must praise the Holy One, day and night. He knows all of our transgressions and does not divulge any of them. The person, who sees a small sin committed by his friend, tells it to all the people in order to shame him. Therefore the verse says, “when he speaks with his enemies in the gate” [Psalms, 127:5]. That is to say, when the Holy One is the landlord, He does not divulge what he does. The enemies do not talk about him in the market where they used to talk about people. They would gather and gossip about how everyone behaved. Therefore, the verse says, “like arrows in the hands of a warrior” [Psalms, 27:4]. That is to say, gossip that one talks about in the market where householders gather and discuss everyone in the community. This is the meaning in the verse of “in the gate.” That is to say, they talk about what someone eats and drinks. This is like an arrow that is shot far and hits a distant person with evil words.
