Ibn Ezra on Numbers 6:19/אבן עזרא על במדבר ו׳:י״ט

אבשלה. פירוש והיא בשלה:
1WHEN IT IS SODDEN. The meaning of beshelah (when it is sodden) is, and it46 is sodden.47. This literally means the shoulder cooked. Hence I.E.’s comment.
בהתגלחו את נזרו. הנה אות כי קדש הוא שב אל הזרוע כי הוא עיקר או ישוב הוא על המונף כלו:
2AFTER HE HATH SHAVEN HIS CONSECRATED HEAD. This is a sign that the kodesh hu (this is holy) (v. 20) refers to the word shoulder,48 for that is the main organ that is being waved. On the other hand, the word hu (this)49. may refer to all that is waved.50 is a singular. Thus kodesh hu refers to all that is being waved.
