וְקֶ֤צֶף גָּדוֹל֙ אֲנִ֣י קֹצֵ֔ף עַל־הַגּוֹיִ֖ם הַשַּֽׁאֲנַנִּ֑ים אֲשֶׁ֤ר אֲנִי֙ קָצַ֣פְתִּי מְּעָ֔ט וְהֵ֖מָּה עָזְר֥וּ לְרָעָֽה׃
Rashi on Zechariah
that are at ease Concerning whom these [messengers] say that they sit still and are at rest.
Radak on Zechariah
"I am sore displeased heathen at ease" that is, as is said above, " Sitteth still, and is at rest."
