וְאָב֤וּס עַמִּים֙ בְּאַפִּ֔י וַאֲשַׁכְּרֵ֖ם בַּחֲמָתִ֑י וְאוֹרִ֥יד לָאָ֖רֶץ נִצְחָֽם׃ (ס)
Rashi on Isaiah
And I trod Heb. וְאָבוּס. An expression of wallowing in blood and treading with the feet. Comp. (Ezekiel 16:6) “wallowing (מִתְבּוֹסֶסֶת) in your blood.” Comp. also (Jer. 12:10): “They trod (בֹּסְסוּ) My field.”
