Now it came to pass the same night that the LORD said to him, “Take your father’s young bull, the second bull of seven years old, and tear down the altar of Baal that your father has, and cut down the wooden image that is beside it…” (Judges 6.25).
What was the significance of the second bull of seven years of age? I do not know other than the fact that the Lord would use this bull and Gideon’s actions to turn the hearts of the Israelites away from idolatry and back to worshiping the one true and living God, Yahweh of Hosts!
Seven often represents completeness or perfection, and that would hold true in this case, because converting people from idolatry to worshiping the true God is the greatest and most complete work that one can do.
