Jonah resents God's mercy toward people he believes unworthy; the elder brother resents the father's mercy toward his brother. Both narratives end with divine/paternal reasoning that exposes the hearer's attitude toward grace.

God’s compassion for Nineveh fits the Abrahamic horizon in which blessing through Abraham’s line ultimately reaches all families of the earth. Jonah never quotes Genesis 12, so the relationship is best read as canonical promise development rather than direct allusion.

Jonah ends with YHWH pitying the great Assyrian city; Isaiah 19 later imagines Assyria, Egypt, and Israel together under God’s blessing.

Jonah ends with YHWH defending compassion for a Gentile city; Micah immediately turns the prophetic spotlight onto Samaria and Jerusalem, showing that divine mercy and judgment are not tribal possessions.

Jonah’s closing concern for Nineveh contributes to the nations trajectory that Micah develops into a vision of many peoples streaming to YHWH’s mountain for instruction and peace. Jonah’s concern for a Gentile city and Micah’s vision of many peoples seeking the LORD belong to a developing biblical nations trajectory. The relationship should be stated only as strongly as the approved evidence allows.
