'God of Your Father' in the Bible

And behold, we have God with us at our head, and his priests, and the loud-sounding trumpets to sound an alarm against you. Children of Israel, do not fight with Jehovah the God of your fathers; for ye shall not prosper.

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

and he said to them, Hear me, ye Levites: hallow yourselves now, and hallow the house of Jehovah the God of your fathers, and carry forth the filthiness out of the sanctuary.
