Peter, the Chief of the Apostles

Peter, the chief of the apostles, used to divide the proceeds of his fishing into seven parts, and when, having taken one part for each day's use, he arrived at the seventh portion, he knew it was the Sabbath day. Consider this! and then think of his future position; to what glory he attained because the Holy Spirit wrought great works through him. (Abdu'l-Baha, Paris Talks, p. 164)
