Ver. 16. “For He Himself laid down His life for us;” that is, for those who believe; that is, for the apostles. If then He laid down His life for the apostles, he means His apostles themselves: us if he said, We, I say, the apostles, for whom He laid down His life, “ought to lay down our lives for the brethren;” for the salvation of their neighbours was the glory of the apostles.
