וְהַנּוֹתָ֗ר מִן־הַשֶּׁ֙מֶן֙ אֲשֶׁר֙ עַל־כַּ֣ף הַכֹּהֵ֔ן יִתֵּ֖ן עַל־רֹ֣אשׁ הַמִּטַּהֵ֑ר לְכַפֵּ֥ר עָלָ֖יו לִפְנֵ֥י יְהוָֽה׃
And the rest of the oil that is in the priest’s hand he shall put upon the head of him that is to be cleansed, to make atonement for him before the LORD.
Targum Jonathan on Leviticus
And what remaineth of the oil that is upon the priest's hand he shall put upon the head of him who is to be cleansed, to atone for him before the Lord.
