Leviticus 19:32

Aged man. Such are supposed to be possessed of wisdom and experience. The Egyptians and Lacedemonians rose up out of respect to an old man. (Herod., ii. 80.) The Rabbins pretend that a person ought to rise up when the old man is four cubits distant, provided he be, as he ought, a man of wisdom; for otherwise he is entitled to no honour. But this would be making inferior judges of their merit. The Chaldean, Philo, &c., comprise those "learned in the law," under the name of old men.
