AYO
(gr. «paidagogos»).
He was originally a slave who took his master’s children to school. The law was a schoolmaster to the Jews (not to the Gentiles: Paul speaks in the first person plural, in contrast to the second person plural of Gal. 3:26) until Christ came.
But anyone who had been led to Christ was no longer under this tutor (Gal. 3:24, 25; cp. Rom. 6:14).
