Matthew Henry Commentary 1 Chronicles 15:25-29

"So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of Jehovah out of the house of Obed-edom with joy. And it came to pass, when God helped the Levites that bare the ark of the covenant of Jehovah, that they sacrificed seven bullocks and seven rams. And David was clothed with a robe of fine linen, and all the Levites that bare the ark, and the singers, and Chenaniah the master of the song [with] the singers: and David had upon him an ephod of linen. Thus all Israel brought up the ark of the covenant of Jehovah with shouting, and with sound of the cornet, and with trumpets, and with cymbals, sounding aloud with psalteries and harps. And it came to pass, as the ark of the covenant of Jehovah came to the city of David, that Michal the daughter of Saul looked out at the window, and saw king David dancing and playing; and she despised him in her heart." — 1 Chronicles 15:25-29 (ASV)

It is good to notice the assistance of Divine Providence, even in things which fall within the scope of our natural powers; if God did not help us, we could not stir a step. If we do our religious duties correctly to any degree, we must acknowledge that it was God who helped us; had we been left to ourselves, we would have been guilty of some fatal errors. And everything in which we engage must be done in dependence on the mercy of God through the sacrifice of the Redeemer.
