וַיַּקְרֵ֞ב אֶת־בְּנֵ֣י אַהֲרֹ֗ן וַיִּתֵּ֨ן מֹשֶׁ֤ה מִן־הַדָּם֙ עַל־תְּנ֤וּךְ אָזְנָם֙ הַיְמָנִ֔ית וְעַל־בֹּ֤הֶן יָדָם֙ הַיְמָנִ֔ית וְעַל־בֹּ֥הֶן רַגְלָ֖ם הַיְמָנִ֑ית וַיִּזְרֹ֨ק מֹשֶׁ֧ה אֶת־הַדָּ֛ם עַל־הַֽמִּזְבֵּ֖חַ סָבִֽיב׃
他帶亞倫的兒子們前來，摩西把一些血抹在他們的右耳垂上、右手的大拇指上和右腳的大拇趾上，摩西又把血潑在壇的四周。
Ibn Ezra
He who purifies himself from a corporeal ṣara‘at is like a kohen undergoing consecration [8:24]; for sin is like a spiritual ṣara‘at. thumb denotes the joint of the thumb, which is the origin of all activity right because of the greater strength of the right side.lobe This word’s meaning is evident from context, and it symbolizes that one must attend to what has been commanded.
