'Ark of the Lord' in the Bible

And unto Abiathar the priest said the king, Get thee to Anathoth, unto thine own fields; for thou art worthy of death: but I will not at this time put thee to death, because thou barest the ark of the Lord GOD before David my father, and because thou hast been afflicted in all wherein my father was afflicted.

And they brought up the ark of the LORD, and the tabernacle of the congregation, and all the holy vessels that were in the tabernacle, even those did the priests and the Levites bring up.
