Jonah 4:2

Exodus 34:6-7 NIV
And he passed in front of Moses, proclaiming, “The Lord, the Lord, the compassionate and gracious God, slow to anger, abounding in love and faithfulness, maintaining love to thousands, and forgiving wickedness, rebellion and sin. Yet he does not leave the guilty unpunished; he punishes the children and their children for the sin of the parents to the third and fourth generation.”

Joel 2:13-14 NIV
Rend your heart and not your garments. Return to the Lord your God, for he is gracious and compassionate, slow to anger and abounding in love, and he relents from sending calamity. Who knows? He may turn and relent and leave behind a blessing — grain offerings and drink offerings for the Lord your God.

Numbers 14:18-19 NIV
‘The Lord is slow to anger, abounding in love and forgiving sin and rebellion. Yet he does not leave the guilty unpunished; he punishes the children for the sin of the parents to the third and fourth generation.’ In accordance with your great love, forgive the sin of these people, just as you have pardoned them from the time they left Egypt until now.”
