Mateo 10:38

Doth not take his cross

(ου λαμβανε τον σταυρον αυτου). The first mention of cross in Matthew. Criminals were crucified in Jerusalem. It was the custom for the condemned person to carry his own cross as Jesus did till Simon of Cyrene was impressed for that purpose. The Jews had become familiar with crucifixion since the days of Antiochus Epiphanes and one of the Maccabean rulers (Alexander Jannaeus) had crucified 800 Pharisees.

It is not certain whether Jesus was thinking of his own coming crucifixion when he used this figure, though possible, perhaps probable. The disciples would hardly think of that outcome unless some of them had remarkable insight.
