'Locked' in the Bible

On that same first day of the week, when it was evening and, for fear of the Jews, the doors of the house where the disciples were, were locked, Jesus came and stood in their midst, and said to them, "Peace be to you!"

A week later the disciples were again in the house, and Thomas was with them, when Jesus came--though the doors were locked--and stood in their midst, and said, "Peace be to you."

saying, "The jail we found quite safely locked, and the warders were on guard at the doors, but upon going in we found no one there."

For God has locked up all in the prison of unbelief, that upon all alike He may have mercy.
