When God helped the Levites; either,
1. By giving them strength to carry their burden; or rather,
2. By encouraging them in their work with some comfortable sign of his presence with them, and approbation of their work and manner of carrying the ark: when they saw that he did not cut off any of the persons employed, as he had done before, but spared and favoured them; which they perceived when they had gone six paces, as appears by 2 Samuel 6:13.
