Psalms 106:23, 30

Therefore He said He would destroy them, [And He would have done so] had not Moses, His chosen one, stepped into the gap before Him, To turn away His wrath from destroying them. [Ex 32:10, 11, 32]

Then Phinehas [the priest] stood up and interceded, And so the plague was halted. [Num 25:7, 8]
