Num 6:19

וְלָקַ֨ח הַכֹּהֵ֜ן אֶת־הַזְּרֹ֣עַ בְּשֵׁלָה֮ מִן־הָאַיִל֒ וְֽחַלַּ֨ת מַצָּ֤ה אַחַת֙ מִן־הַסַּ֔ל וּרְקִ֥יק מַצָּ֖ה אֶחָ֑ד וְנָתַן֙ עַל־כַּפֵּ֣י הַנָּזִ֔יר אַחַ֖ר הִֽתְגַּלְּח֥וֹ אֶת־נִזְרֽוֹ׃

And the priest is to take the boiled shoulder from the ram, one unleavened cake from the basket, and one unleavened wafer, and put them into the hands of the Nazirite who has just shaved the hair of his consecration.
