Zealous for God who is jealous

In discussing jealousy of God and how that makes us to be zealous for God, J. I Packer writes about Phinehas:

When Israel had provoked God to anger by idolatry and prostitution, and Moses had sentenced the offenders to death, and the people were in tears, and a man chose that moment to swagger up with a Midianite party-girl on his arm, and Phinehas, almost beside himself with despair, speared them both, God commended Phinehas as having been 'jealous for his God', 'jealous with my jealousy ... so that I consumed not the children of Israel in my jealousy' (Num. 25:11, 13, RV)
- p. 197, from Knowing God by J. I. Packer

Phinehas, definitely an inspiring figure I find in the bible.
