Side-ring EXTRA · Tevilah from white to golden garments
Torah Temimah is silent on 16:24. Rashi (Toras Kohanim / Yoma 32a) derives from this verse that immersion is required when the Kohen Gadol changes from the white linen garments back to the golden garments.
English: Above we learned that when he changes from golden garments to white garments he requires immersion; here we learn that when he changes from white garments to golden garments he likewise requires immersion.
Symmetric tevilah at every garment change
Every transition between the white (inner) service and the golden (outer) service on Yom Kippur is marked by immersion. The five immersions of the day are thus structurally required by the garment changes themselves.
