“Grey hair is a crown of glory.
It is gained in a righteous life.
Whoever is slow to anger
Is better than the mighty.
The one whose temper is controlled
Is better than one who captures a city.
The lot is cast into the lap.
But the decision is Yahweh’s alone.”
Grey was a crown of glory because you had to be righteous to live a long life. If you were slow to anger, you were stronger than the mighty ones. You were better than someone who captured a city. Finally, the lot that was chosen from the priestly ephod was really the decision of Yahweh alone. Thus casting lots was a way of putting the decision in God’s hands, not human hands.
