וְעַסּוֹתֶ֣ם רְשָׁעִ֔ים כִּֽי־יִהְי֣וּ אֵ֔פֶר תַּ֖חַת כַּפּ֣וֹת רַגְלֵיכֶ֑ם בַּיּוֹם֙ אֲשֶׁ֣ר אֲנִ֣י עֹשֶׂ֔ה אָמַ֖ר יְהוָ֥ה צְבָאֽוֹת׃ (פ)
(4,3) Y hollaréis á los malos, los cuales serán ceniza bajo las plantas de vuestros pies, en el día que yo hago, ha dicho SEÑOR de los ejércitos.

And you shall crush and you shall press. This is an expression of pressing, similar to (Ezek. 23: 8) “they pressed their virgin breasts.”
Tze'enah Ure'enah
“You will trample the evildoers, for thy will be dust beneath your feet” [3:21]. You righteous ones will trample the evildoers with your feet. Then the evildoers will be dust under the feet of the righteous. The righteous ones have lain under the feet of the evildoers long enough.
