Theophylact of Bulgaria
You have seen Paul's wise discernment. To bind the Gentiles to himself and dispose them favorably, and also not to scatter their attention by giving them everything at once, he first uttered several hints and left them unresolved. By this he awakened in the Gentiles a desire to hear him another time. He said that forgiveness of sins was being proclaimed to them, but he did not explain how this forgiveness would be accomplished. He did not baptize them at once, because it was not the proper time. "On the next Sabbath" means "on the coming Sabbath," as is clear below.
