A.T. Robertson Commentary Matthew 27:64

"Command therefore that the sepulchre be made sure until the third day, lest haply his disciples come and steal him away, and say unto the people, He is risen from the dead: and the last error will be worse than the first." — Matthew 27:64 (ASV)

The last error (η εσχατη πλανη). The last delusion, imposture (Weymouth), fraud (Moffatt). Latin error is used in both senses, from errare, to go astray. The first fraud was belief in the Messiahship of Jesus, the second belief in his resurrection.
