When Israel, the covenant people, forsook her Maker—her husband—she suffered the consequences of her abandonment and incurred his “little wrath” for a moment, but his kindly, merciful promise to gather Israel is as sure as his promise to send no more flood. Verse 9 confirms the historicity of the Flood. Besides the biblical account, we have an additional three witnesses of the Flood in Alma 10:22; 3 Nephi 22:9; and Ether 6:7; 13:2.
Kindness is a good measure of the greatness of a person, and God is great.
