Saying, Did not we straitly command you that ye should not teach in this name? and, behold, ye have filled Jerusalem with your doctrine, and intend to bring this man's blood upon us.
Saying, Did not we straitly (or strictly) command you. The true text here would seem to be not in the form of a question, but of an affirmation: 'We strictly commanded you' [omitting ou (G3756), which crept naturally in after epeerooteesen (G1905) of Acts 5:27],
That ye should not teach in this name? and, behold, ye have filled Jerusalem with your doctrine. Noble witness this, both to the success of their preaching, and (for the reason mentioned in Acts 4:4) to the truth of their testimony, from reluctant lips!
And intend to bring this man's blood upon us. They avoid (as Bengel remarks) naming Him whom the apostle gloried in holding up before them. In speaking thus, of bringing His blood upon them, they seem haunted by disagreeable recollections of their own recent imprecation, "His blood be on us and on our children" (Matthew 27:25), and perhaps of the traitor's words as he threw down their money, "I have sinned, in that I have betrayed the innocent blood" (Matthew 27:41).
