2 Samuel 6:3-4

3They had mounted the ark of God on 1a new cart and moved it from the house of Abinadab, which was on the hill; and Uzzah and Ahio, the sons of Abinadab, were leading the new cart.

4So 2they brought it with the ark of God from the house of Abinadab, which was on the hill; and Ahio was walking ahead of the ark.
