How did Phinehas intervene to halt the punishment? (Psalm 106:30)

28 
They yoked themselves to the Baal of Peor
    and ate sacrifices offered to lifeless gods;
29 
they aroused the Lord’s anger by their wicked deeds,
    and a plague broke out among them.
30 
But Phinehas stood up and intervened,
    and the plague was checked.
31 
This was credited to him as righteousness
    for endless generations to come.
