Matthew Henry on 2 Samuel 6:12-19
We have here the second attempt to bring the ark home to the city of David; and this succeeded, though the former miscarried.
I. It should seem the blessing with which the house of Obed-edom was blessed for the ark's sake was a great inducement to David to bring it forward; for when that was told him (Sa2 6:12) he hastened to fetch it to him.
