Jueces 6:28

The second bullock was offered - It appears that the second bullock was offered because it was just seven years old, Judges 6:25 , being calved about the time that the Midianitish oppression began; and it was now to be slain to indicate that their slavery should end with its life. The young bullock, Judges 6:25 , is supposed to have been offered for a peace-offering; the bullock of seven years old, for a burnt-offering.
