וַיִּשְׁטֹ֨ף אֶת־הָרֶ֜כֶב עַ֣ל ׀ בְּרֵכַ֣ת שֹׁמְר֗וֹן וַיָּלֹ֤קּוּ הַכְּלָבִים֙ אֶת־דָּמ֔וֹ וְהַזֹּנ֖וֹת רָחָ֑צוּ כִּדְבַ֥ר יְהוָ֖ה אֲשֶׁ֥ר דִּבֵּֽר׃
And they washed the chariot by the pool of Samaria; and the dogs licked up his blood; the harlots also washed themselves there; according unto the word of the LORD which He spoke.
Ibn Ezra
The ’alef in the word your weapons (from “and they washed their weapons” [I Kings 22: 38]) is extraneous.
