slow to anger: God's patience with disobedience is linked to his faithful love (Exodus 34:6; Numbers 14:18; Psalm 103:8; Joel 2:13). This trait disappointed Jonah, who wanted Nineveh destroyed immediately (Jonah 4:2). Because God is patient, he sometimes delays the deserved punishment of sinners (Nehemiah 9:29–30; Romans 2:4; 2 Peter 3:9), but those who continue to sin will ultimately face God's judgment (Exodus 34:7; Romans 14:10; 2 Corinthians 5:10; Revelation 14:6–7).
the whirlwind and storm: This imagery describes the fury of God's judgment against the wicked (see also Isaiah 29:6).
