"So give the order for the tomb to be made secure until the third day. Otherwise, his disciples may come and steal the body and tell the people that he has been raised from the dead. This last deception will be worse than the first."
NIV
Therefore give an order to have the tomb made secure and safeguarded until the third day, for fear that His disciples will come and steal Him away and tell the people that He has risen from the dead, and the last deception and fraud will be worse than the first.
AMP
Command therefore that the sepulchre be made sure until the third day, lest his disciples come by night, and steal him away, and say unto the people, He is risen from the dead: so the last error shall be worse than the first.
