'Ark of the Lord' in the Bible

Then David ordered that the Ark of God was to be carried by no one except the descendants of Levi, because the LORD had chosen them to carry the ark of the LORD and to serve him forever.

David assembled all of Israel in Jerusalem to bring up the ark of the LORD to its proper place that he had prepared for it.

and addressed them: "As leaders of your Levitical families, set yourselves apart, both you and your relatives, so you can be qualified to bring up the ark of the LORD God of Israel to the place I've prepared for it.

So the priests and descendants of Levi set themselves apart to carry the ark of the LORD God of Israel.

In the presence of the ark of the LORD, he appointed some of the descendants of Levi to minister continually by remembering, giving thanks, and praising the LORD God of Israel.

After David had settled down to live in his palace, he spoke with the prophet Nathan. "Look, here I am living in this cedar palace, but the ark of the LORD's covenant remains surrounded by curtains!"
