Charles Ellicott Commentary 1 Chronicles 13:7

"And they carried the ark of God upon a new cart, [and brought it] out of the house of Abinadab: and Uzza and Ahio drove the cart." — 1 Chronicles 13:7 (ASV)

Abridged form of the fuller text preserved in 2 Samuel 6:3 (see Notes there).

Drave. —Were driving. 2 Samuel 6:4, is wholly omitted by the Chronicles. “Ahio” may mean his brother, or, with different points, his brothers (so Septuagint and Syriac).
