'God of Your Fathers' in the Bible

And, behold, God himself is with us for our captain, and his priests with sounding trumpets to cry alarm against you. O children of Israel, fight ye not against the LORD God of your fathers; for ye shall not prosper.

But a prophet of the LORD was there, whose name was Oded: and he went out before the host that came to Samaria, and said unto them, Behold, because the LORD God of your fathers was wroth with Judah, he hath delivered them into your hand, and ye have slain them in a rage that reacheth up unto heaven.

And said unto them, Hear me, ye Levites, sanctify now yourselves, and sanctify the house of the LORD God of your fathers, and carry forth the filthiness out of the holy place.
