אַל־תִּתֵּ֣ן יְ֭הוָה מַאֲוַיֵּ֣י רָשָׁ֑ע זְמָמ֥וֹ אַל־תָּ֝פֵ֗ק יָר֥וּמוּ סֶֽלָה׃
Não levantem a cabeça os que me cercam; cubra-os a maldade dos seus lábios.
Rashi on Psalms
for they are constantly haughty Heb. ירומו סלה, because they are arrogant always. Our Rabbis, however (Gen. Rabbah 75:9) explained זממוֹ as an expression of a bit that muzzles the camel, and it is a mishnaic expression.
Rashi on Psalms
do not take out Heb. אל תפק, Do not take it out of his jaws.
