John Wesley on Deuteronomy 10:6

This following history comes in manifestly by way of parenthesis, as may appear from Deu 10:10, where he returns to his former discourse; and it seems to be here inserted as an evidence of God's gracious answer to Moses's prayers, and of his reconciliation to the people, notwithstanding their late and great provocation. For, saith he, after this they proceeded by God's guidance in their journeys, and though Aaron died in one of them, yet God made up that breach, and Eleazar came in his place, and ministered as priest, one branch of which office was to intercede for the people.
