'Fathers' in the Bible

'Yahweh [is] {slow to anger} and great of loyal love, {forgiving} sin and rebellion; but surely he leaves nothing unpunished, visiting the sin of the fathers on the sons to the third and fourth generations.'

This is what your fathers did when I sent them from Kadesh Barnea to see the land.

Behold, you stand in the place of your fathers, a brood of sinful men, to increase still more {Yahweh's fierce anger} against Israel.
