'Secure' in the Bible

So give orders to secure the tomb until the third day. Otherwise his disciples may come and steal his body and say to the people, 'He has been raised from the dead,' and the last deception will be worse than the first."

Pilate said to them, "Take a guard of soldiers. Go and make it as secure as you can."

So they went with the soldiers of the guard and made the tomb secure by sealing the stone.
