רְתֹ֧ם הַמֶּרְכָּבָ֛ה לָרֶ֖כֶשׁ יוֹשֶׁ֣בֶת לָכִ֑ישׁ רֵאשִׁ֨ית חַטָּ֥את הִיא֙ לְבַת־צִיּ֔וֹן כִּי־בָ֥ךְ נִמְצְא֖וּ פִּשְׁעֵ֥י יִשְׂרָאֵֽל׃
Isingkaw mo sa matutuling kabayo ang karwahe, ikaw na naninirahan sa Laquis; siya ang pinagmulan ng kasalanan ng anak na babae ng Zion, sapagkat sa iyo natagpuan ang mga pagsalangsang ng Israel.
Rashi
Hitch the chariot to the swift steeds Heb. רְתֹם הַמֶּרְכָּבָה לַרֶכֶשׁ. Hitch the chariot to the רֶכֶשׁ, which is swift to run, and you shall escape. The word רֶכֶשׁ is explained by Dunash (Teshuvoth Dunash p. 69) as an Arabic word.
