Iscariot was chosen for the job before he was born. Iscariot is not a Jewish name and researchers, when I researched it, can't find a similar name in the region or in this world. His head was with Satan; I wouldn't want to find out.
Psalms 41:9
Even my own familiar friend in whom I trusted,
Who ate my bread,
Has lifted up his heel against me.
John 13:18 - “I do not speak concerning all of you. I know whom I have chosen; but that the Scripture may be fulfilled, ‘He who eats bread with Me has lifted up his heel against Me.’
