While Moses was on the mountain, the Israelites chose to make an idol for themselves and worship it even after hearing the ten commandments from God, seeing His power. God is angry and will destroy the Israelites but Moses begs God to have mercy and remember His promise to Abraham, Isaac, and Israel (Jacob). After Moses comes down from the mountain, the idol is destroyed and God punishes the people but having compassion, or caring for the Israelites, He does not destroy everyone.
