And David was afraid of the LORD that day, and said, How shall the ark of the LORD come to me?

Jamieson-Fausset-Brown Bible Commentary

9, 10. David was afraid of the Lord that day, &c.-His feelings on this alarming judgment were greatly excited on various accounts, dreading that the displeasure of God had been provoked by the removal of the ark, that the punishment would be extended to himself and people, and that they might fall into some error or neglect during the further conveyance of the ark. He resolved, therefore, to wait for more light and direction as to the path of duty. An earlier consultation by Urim would have led him right at the first, whereas in this perplexity and distress, he was reaping the fruits of inconsideration and neglect.

Matthew Henry's Concise Commentary

6:6-11 Uzzah was struck dead for touching the ark. God saw presumption and irreverence in Uzzah's heart. Familiarity, even with that which is most awful, is apt to breed contempt. If it were so great a crime for one to lay hold on the ark of the covenant who had no right to do so, what is it for those to lay claim to the privileges of the covenant that come not up to the terms of it? Obed-edom opened his doors without fear, knowing the ark was a savour of death unto death to those only who treated it wrong. The same hand that punished Uzzah's proud presumption, rewarded Obed-edom's humble boldness. Let none think the worse of the gospel for the judgments on those that reject it, but consider the blessings it brings to all who receive it. Let masters of families be encouraged to keep up religion in their families. It is good to live in a family that entertains the ark, for all about it will fare the better.
