“And  refused to obey, neither were mindful of Thy wonders that Thou didst among them; but hardened their necks, and in their rebellion appointed a captain to return to their bondage: but Thou art a God ready to pardon, gracious and merciful, slow to anger, and of great kindness, and forsookest them not.” – Neh. 9:17

This is God’s overflowing and everflowing mercy. He is ready to pardon.
