International Standard Bible Encyclopedia
kris'-pus (Krispos, "curled"): One of the small number baptized by Paul among the Corinthian Christians (1Co 1:14). He had been ruler of the Jewish synagogue, but he "believed in the Lord with all his house"; and, following Paul, withdrew from the synagogue (Ac 18:7,8). He seems to have been succeeded by Sosthenes (Ac 18:17). According to tradition he became bishop of Aegina.
