I-Samuel

And one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped, and fled after David.

Therefore David enquired of the Lord, saying, Shall I go and smite these Philistines? And the Lord said unto David, Go, and smite the Philistines, and save Keilah.

And David knew that Saul secretly practised mischief against him; and he said to Abiathar the priest, Bring hither the ephod.

And these are the garments which they shall make; a breastplate, and an ephod, and a robe, and a broidered coat, a mitre, and a girdle: and they shall make holy garments for Aaron thy brother, and his sons, that he may minister unto me in the priest’s office.

And thou shalt put in the breastplate of judgment the Urim and the Thummim; and they shall be upon Aaron’s heart, when he goeth in before the Lord: and Aaron shall bear the judgment of the children of Israel upon his heart before the Lord continually.
