Leviticus 6:15
JPS-1917וְהַכֹּהֵ֨ן הַמָּשִׁ֧יחַ תַּחְתָּ֛יו מִבָּנָ֖יו יַעֲשֶׂ֣ה אֹתָ֑הּ חׇק־עוֹלָ֕ם לַיהֹוָ֖ה כָּלִ֥יל תׇּקְטָֽר׃
And the anointed priest that shall be in his stead from among his sons shall offer it, it is a due for ever; it shall be wholly made to smoke unto the LORD.
Rashi Commentary
המשיח תחתיו מבניו is the same as המשיח מבניו תחתיו THE PRIEST THAT IS ANOINTED FROM AMONGST HIS SONS IN HIS STEAD. כליל תקטר IT SHALL WHOLLY ASCEND IN FUMES — The קמץ (the altar's share) is not taken off from it so that there can be any remaining of it to be eaten by the priests, but the whole of it is burnt entire. Similarly the next verse points out that every free-will meal-offering of a priest (i. e. such offering in general) shall be wholly burnt (cf. Sifra, Tzav, Chapter 5 3).

And the priest of his sons that is anointed in his place shall offer it: it is a statute for ever to the Lord; it shall be wholly burnt.
