John 20:24

But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.

Ver. 24. But Thomas, one of the twelve] A man cannot be wilfully absent from the public assemblies but once, without great danger and damage. Thomas was absent perhaps about some weighty cause. It may be he lurked and lay close for fear of the Jews; or it may be he was providing, and settling his own private affairs, now his Master was slain; but whatever the cause was, the effect was grievous; he was woefully hardened.
