2 Samuel 15:24

And Zadok the son of Ahitub, and Ahimelech the son of Abiathar, were the priests; and Seraiah was the scribe;

And when Aaron and his sons have made an end of covering the sanctuary, and all the vessels of the sanctuary, as the camp is to set forward; after that, the sons of Kohath shall come to bear it: but they shall not touch any holy thing, lest they die. These things are the burden of the sons of Kohath in the tabernacle of the congregation.

And Sheva was scribe: and Zadok and Abiathar were the priests:

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

It shall be for the priests that are sanctified of the sons of Zadok; which have kept my charge, which went not astray when the children of Israel went astray, as the Levites went astray.

The king said also unto Zadok the priest, Art not thou a seer? return into the city in peace, and your two sons with you, Ahimaaz thy son, and Jonathan the son of Abiathar.

Then David said, None ought to carry the ark of God but the Levites: for them hath the LORD chosen to carry the ark of God, and to minister unto him for ever.

And they commanded the people, saying, When ye see the ark of the covenant of the LORD your God, and the priests the Levites bearing it, then ye shall remove from your place, and go after it.

And seven priests shall bear before the ark seven trumpets of rams’ horns: and the seventh day ye shall compass the city seven times, and the priests shall blow with the trumpets.

And Joshua spake unto the priests, saying, Take up the ark of the covenant, and pass over before the people. And they took up the ark of the covenant, and went before the people.

But Zadok the priest, and Benaiah the son of Jehoiada, and Nathan the prophet, and Shimei, and Rei, and the mighty men which belonged to David, were not with Adonijah.

And Joshua the son of Nun called the priests, and said unto them, Take up the ark of the covenant, and let seven priests bear seven trumpets of rams’ horns before the ark of the LORD.

And the ark of God was taken; and the two sons of Eli, Hophni and Phinehas, were slain.

And the king put Benaiah the son of Jehoiada in his room over the host: and Zadok the priest did the king put in the room of Abiathar.

And hast thou not there with thee Zadok and Abiathar the priests? therefore it shall be, that what thing soever thou shalt hear out of the king’s house, thou shalt tell it to Zadok and Abiathar the priests.

But unto the sons of Kohath he gave none: because the service of the sanctuary belonging unto them was that they should bear upon their shoulders.

And it was so, that when they that bare the ark of the LORD had gone six paces, he sacrificed oxen and fatlings.
