Charles Spurgeon Commentary John 13:2

"And during supper, the devil having already put into the heart of Judas Iscariot, Simon`s [son], to betray him," — John 13:2 (ASV)

And supper being ended,

I suppose that was the Paschal supper.

The devil having now put into the heart of Judas Iscariot, Simon's son, to betray him;

What a horrible purpose for Satan to put into the heart of Judas even in the presence of Jesus! I hope that the devil will not put any such purpose into your hearts or into mine while we are in this house of prayer, but no place is sacred from his intrusion; he will come in anywhere. Even where Christ himself is at the head of the table, Judas may be sitting at that same table, and Satan may then and there put into his heart the horrible purpose of betraying his Master.
