Numbers 25:7

And Eleazar Aaron’s son took him one of the daughters of Putiel to wife; and she bare him Phinehas: these are the heads of the fathers of the Levites according to their families.

And the evil spirit from the LORD was upon Saul, as he sat in his house with his javelin in his hand: and David played with his hand.

And Phinehas, the son of Eleazar, the son of Aaron, stood before it in those days,) saying, Shall I yet again go out to battle against the children of Benjamin my brother, or shall I cease? And the LORD said, Go up; for to morrow I will deliver them into thine hand.

Then stood up Phinehas, and executed judgment: and so the plague was stayed.
