Commentary for Leviticus 8:23

וַיִּשְׁחָ֓ט ׀ וַיִּקַּ֤ח מֹשֶׁה֙ מִדָּמ֔וֹ וַיִּתֵּ֛ן עַל־תְּנ֥וּךְ אֹֽזֶן־אַהֲרֹ֖ן הַיְמָנִ֑ית וְעַל־בֹּ֤הֶן יָדוֹ֙ הַיְמָנִ֔ית וְעַל־בֹּ֥הֶן רַגְל֖וֹ הַיְמָנִֽית׃

And when it was slain, Moses took of the blood thereof, and put it upon the tip of Aaron’s right ear, and upon the thumb of his right hand, and upon the great toe of his right foot.
