King James Version (KJV)
And they shall be as mighty {men}, which tread down {their enemies} in the mire of the streets in the battle: and they shall fight, because the LORD {is} with them, and the riders on horses shall be confounded. {the riders...: or, they shall make the riders on horses ashamed}
Modern English
They shall be as mighty men, treading down muddy streets in the battle; and they shall fight, because Yahweh is with them; and the riders on horses will be confounded.
Hebrew
וְהָי֨וּ כְגִבֹּרִ֜ים בּוֹסִ֨ים בְּטִ֤יט חוּצוֹת֙ בַּמִּלְחָמָ֔ה וְנִ֨לְחֲמ֔וּ כִּ֥י יְהוָ֖ה עִמָּ֑ם וְהֹבִ֖ישׁוּ רֹכְבֵ֥י סוּסִֽים׃
