פּירוש אויף שמות 28:41

והלבשת אתם את אהרן AND THOU SHALT PUT THEM ON AARON — i. e. those which are mentioned in connection with Aaron: the breast-plate, the ephod, the Robe, the inner garment of checker-work, the mitre, the girdle and the Plate, and the breeches which are prescribed later for all of them (for all the priest’s and therefore for Aaron also).

וקדשת אותם, “you will sanctify them.” This refers to an oral sanctification. (Ibn Ezra) It is comparable to the oral declaration of someone being declared ritually impure by the priest when with the skin disease tzoraat, in Leviticus 13,44.

AND THOU SHALT PUT THEM UPON AARON THY BROTHER AND UPON HIS SONS WITH HIM — “those which are mentioned in connection with them.” This is Rashi’s language. The meaning of with him is that they were all clothed with the priestly garments and anointed on the same day.

ואת בניו אתו [AND THOU SHALT PUT THEM ON AARON …] AND ON HIS SONS WITH HIM — i. e. put on them those garments which are prescribed for them.
