'Ark of the Covenant' in the Bible

At that time Yahweh set apart the tribe of Levi, to bear the ark of the covenant of Yahweh, to stand before Yahweh to minister to him, and to bless in his name, to this day.

Moses wrote this law, and delivered it to the priests the sons of Levi, who bore the ark of the covenant of Yahweh, and to all the elders of Israel.

that Moses commanded the Levites, who bore the ark of the covenant of Yahweh, saying,

"Take this book of the law, and put it by the side of the ark of the covenant of Yahweh your God, that it may be there for a witness against you.
