Judas Iscariot; so called, to distinguish him from another Judas, an apostle; Matthew 10:4.
Simon's [son]; this is omitted in the Vulgate Latin, Syriac, Persic, and Ethiopic versions; John 13:2;
which should betray him; and so he did; this was pre-determined by God, foretold in prophecy, and foreknown by Christ; and is observed here, to show the temper and character of the man.
