Numbers 25:11 recounts Phinehas' zeal that turned away God's wrath after the Midianite sin—the very reason God later commands vengeance on Midian in verse 3.

Psalm 149:7 says 'to execute vengeance on the nations' — the same phrase used here for the LORD's vengeance, a strong thematic link.

2 Kings 9:7 commissions Jehu to avenge the blood of prophets—another instance of God appointing someone to execute vengeance, similar to the Midian command.

2 Kings 10:30 commends Jehu for carrying out God's judgment on Ahab's house—parallel to the divine approval of the Midian vengeance in Numbers 31.

Jeremiah 46:10 describes a day of vengeance for the LORD, echoing the same theme of divine vengeance against enemies as here.

Jeremiah 50:28 proclaims vengeance for the LORD's temple, paralleling the command to execute the LORD's vengeance on Midian.
