And the people believed; and when they heard that the LORD had visited the people of Israel and that he had seen their affliction, they bowed their heads and worshiped.
31. And the people believed. Either this is a synecdoche, a part of the people being put for the whole, or else Moses signifies that after the announcement was published, all with one consent embraced the message of their deliverance. I prefer the former meaning; because their solemn adoration is immediately subjoined, which could only have taken place in a public assembly.
Moses neglected to circumcise his son, likely because he was too fond of his Midianite wife and too indulgent of her will, and so God met him in anger to kill him. Omissions are sins; the neglect of the covenant's seals shows we undervalue the promises and despise the conditions. Even good men grow slack in duty when cut off from the company of the faithful.
