Israel rejected the LordJesusChrist, denying His deity, crucifying Him and lying about His resurrection.
Those who are saved are saved by the blood of Christ Jesus and the WordOfTheirTestimony.
Those that are damned -> fail the test of faith in the Saviour -> deny that He is the TrueAndLivingGod and -> may slander Him with their words.
In either event they carry their burden to the LakeOfFire.
