'Secure' in the Bible

Command therefore that the tomb be made secure until the third day, lest perhaps his disciples come at night and steal him away, and tell the people, 'He is risen from the dead;' and the last deception will be worse than the first."

Pilate said to them, "You have a guard. Go, make it as secure as you can."

So they went with the guard and made the tomb secure, sealing the stone.
