'Locked' in the Bible

Herod added this to them all: He locked up John in prison.

On the evening of that day, the first day of the week, the disciples had gathered together and locked the doors of the place because they were afraid of the Jewish leaders. Jesus came and stood among them and said to them, "Peace be with you."

Eight days later the disciples were again together in the house, and Thomas was with them. Although the doors were locked, Jesus came and stood among them and said, "Peace be with you!"

"We found the jail locked securely and the guards standing at the doors, but when we opened them, we found no one inside."

For if God did not spare the angels who sinned, but threw them into hell and locked them up in chains in utter darkness, to be kept until the judgment,

You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.

The angel then threw him into the abyss and locked and sealed it so that he could not deceive the nations until the one thousand years were finished. (After these things he must be released for a brief period of time.)
