And Crispus, the chief ruler of the synagogue, believed on the Lord with all his house; and many of the Corinthians hearing believed, and were baptized.
Note 7 at Ac 18:8: As explained in note 1 at Mt 9:18, the chief ruler of the synagogue was a very influential man. Crispus was one of the few people that Paul baptized in Corinth (1Co 1:14). It must have dealt a major blow to the Jews who rejected the Gospel to see their chief ruler converted. We can see in Ac 18:17 that Sosthenes succeeded Crispus as chief ruler of the synagogue and was later converted to faith in Jesus also (1Co 1:1).
