Acts 5:5

And Ananias fell down and expired — And this severity was not only just, considering that complication of vain glory, covetousness, fraud, and impiety, which this action contained: but it was also wise and gracious, as it would effectually deter any others from following his example. It was likewise a convincing proof of the upright conduct of the apostles, in managing the sums with which they were intrusted; and in general of their Divine mission. For none can imagine that Peter would have had the assurance to pronounce, and much less the power to execute such a sentence, if he had been guilty himself of a fraud of the same kind; or had been belying the Holy Ghost in the whole of his pretensions to be under his immediate direction.
