Exodus 8:18a And the magicians did so with their enchantments to bring forth lice, but they could not:

Nothing is as funny as when a magician’s prop fails. You are all set to be mystified and then the mystery is exposed in the prop failure. Illusionists are very practiced in their art. They can really be impressive with their sleight of hand work in a close up venue. The better ones can be very convincing. Even though you know it is not real, the eye, because it is slow, can be deceived.

Exodus 8:19a Then the magicians said unto Pharaoh, This is the finger of God:

God does not use props, therefor the props will never fail and God will not be mocked.

Matthew 20:19 and will hand Him over to the Gentiles (Roman authorities) to be mocked and scourged and crucified, and He will be raised [to life] on the third day. AMP

The prop in the crucifixion of Christ was the cross, but it was not God’s prop, it was Rome’s. While it failed for the Romans, it became the very symbol of salvation for those who believe.

Death became a laughing stock that day. The prop failed and the magic trick was exposed. There is life after death, resurrection is real. The finger of God pointed the Way.
