Albert Barnes Commentary 2 Kings 10:22

"And he said unto him that was over the vestry, Bring forth vestments for all the worshippers of Baal. And he brought them forth vestments." — 2 Kings 10:22 (ASV)

The vestry - The sacred robes of the priests of Baal seem to have been made of linen and were probably white. The vestry mentioned here was probably the robe-chamber of the royal palace, from which the king gave a festal garment to each worshipper.
