'God of Your Fathers' in the Bible

Behold, God is with us at our head, and His priests [are here] with their signal trumpets to sound an alarm against you. O sons of Israel, do not fight against the Lord God of your fathers, for you cannot succeed.”

But a prophet of the Lord was there, whose name was Oded; and he went out to meet the army that was returning to Samaria and said to them, “Behold, because the Lord, the God of your fathers, was angry with Judah, He handed them over to you; but you have killed them in a rage that has reached as far as heaven.

Then he said to them, “Levites, listen to me! Now consecrate (dedicate) yourselves and consecrate the house of the Lord, the God of your fathers, and get the filth [of idol worship] out of the Holy Place.
