2 Samuel 15:24-29 - The Priests Offer Sacrifices For David
24 And behold, Zadok and all the Levites were with him and bare the ark of the covenant of God. And when they had fetched down the Ark of God, Abiathar came up, until the people were all come over, out of the city. 25 Then said the king unto Zadok, "Carry the Ark of God again into the city. If I shall find favour in the eyes of the LORD, he will bring me again, and show me both it and the tabernacle thereof also. 26 But and if the Lord thus say - 'I have no pleasure in thee' - behold, here am I, let him do with me what seemeth best in his eyes."
27 The king said also unto Zadok the priest, "Thou art a seer; return therefore into the city in peace. And take your two sons with you: Ahimaaz thy son, and Jonathan the son of Abiathar. 28 And see, I will tarry in the fields of the wilderness until there come some word from you to be told me." 29 And so Zadok and Abiathar carried the Ark of God again to Jerusalem, and they tarried there.
