'Forefathers' in the Bible

Our forefathers worshipped on this mountain, but you Jews say that the place where people must worship is in Jerusalem."

Our forefathers ate the manna in the Desert, as it is written, 'He gave them bread out of Heaven to eat'."

Your forefathers ate the manna in the Desert, and they died.

This is the bread which came down out of Heaven; it is unlike that which your forefathers ate--for they ate and yet died. He who eats this bread shall live for ever."

Consider therefore. Moses gave you the rite of circumcision (not that it began with Moses, but with your earlier forefathers)
