'Trousers' in the Bible

that the priest hath put on his long robe of fine linen, and his fine linen trousers he doth put on his flesh, and hath lifted up the ashes which the fire consumeth with the burnt-offering on the altar, and hath put them near the altar;

a holy linen coat he putteth on, and linen trousers are on his flesh, and with a linen girdle he girdeth himself, and with a linen mitre he wrappeth himself up; they are holy garments; and he hath bathed with water his flesh, and hath put them on.
