The ephod was held in place by shoulder straps, and at the front was a breastplate containing twelve precious stones, representing the twelve tribes of Israel. The ephod was a symbol of the high priest's authority and ritual purity. It was worn during religious ceremonies and was used as a means of communication with God. The ephod was also used in divination, with the high priest using the Urim and Thummim stones within the breastplate to receive guidance from God.
