and they believed. And when they heard that the LORD had attended to the Israelites and had seen their affliction, they bowed down and worshiped.

The sin of Moses, which was neglecting to circumcise his son.

And the people believed: and when they heard that the LORD had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped. (n) So that Moses had experience of God's promise that he would have good success.
