הַכֵּ֣ה תַכֶּ֗ה אֶת־יֹֽשְׁבֵ֛י הָעִ֥יר ההוא [הַהִ֖יא] לְפִי־חָ֑רֶב הַחֲרֵ֨ם אֹתָ֧הּ וְאֶת־כָּל־אֲשֶׁר־בָּ֛הּ וְאֶת־בְּהֶמְתָּ֖הּ לְפִי־חָֽרֶב׃
thou shalt surely smite the inhabitants of that city with the edge of the sword, destroying it utterly, and all that is therein and the cattle thereof, with the edge of the sword.
