1 Kings 10:5

The words "the attendance of the servants [and their clothing]." It seems that Solomon, in his wisdom, had divided into classes all his servants, that is, all the craftsmen that did their duty, so that they might be identifiable from their clothing and uniforms which [indicated] the different classes of the bakers, the cooks, the cupbearers. Everyone was recognizable from his gear.

For the beauty of Wisdom is wondrous, and no one looks upon her without admiration and ecstasy, as it is said of Esther and of Solomon, for "all the earth desired to see Solomon's face"; and the Queen of Sheba "came from the ends of the earth to hear the wisdom of Solomon"; and when she saw "the order of his ministers, and their apparel, and the cupbearers, and the holocausts, which he offered in the house of the Lord: she had no longer any spirit in her."
