1 Chronicles 15:1-2

Young's Literal Translation

15 And he maketh for himself houses in the city of David, and prepareth a place for the ark of God, and stretcheth out for it a tent.

² Then said David, `None [are] to carry the ark of God, except the Levites, for on them hath Jehovah fixed to carry the ark of God, and to serve Him -- unto the age.'
