כִּ֠י הִנְנִ֨י מֵנִ֤יף אֶת־יָדִי֙ עֲלֵיהֶ֔ם וְהָי֥וּ שָׁלָ֖ל לְעַבְדֵיהֶ֑ם וִֽידַעְתֶּ֕ם כִּֽי־יְהוָ֥ה צְבָא֖וֹת שְׁלָחָֽנִי׃ (ס)
For, behold, I will shake My hand over them, and they shall be a spoil to those that served them’; and ye shall know that the LORD of hosts hath sent me.
Rashi on Zechariah
and they shall be prey, etc., to Israel, who are now slaves to them.
