'Ark of the Lord' in the Bible

And David assembled all Israel at Jerusalem to bring up the ark of the Lord to the place which he had prepared for it.

and he said to them, “You are the heads of the fathers’ households of the Levites; consecrate yourselves, both you and your relatives, so that you may bring up the ark of the Lord God of Israel, to the place that I have prepared for it.

So the priests and the Levites consecrated (dedicated) themselves to bring up the ark of the Lord God of Israel.

He appointed some of the Levites to minister before the ark of the Lord and to profess [God’s name] and to thank and praise the Lord, the God of Israel:

and for the altar of incense refined gold by weight; and gold for the model of the chariot of the cherubim that spread their wings and covered the ark of the Lord’s covenant.
