And when his disciples were come to the other side, they had forgotten to take bread.
The disciples crossed over to the other side having forgotten to bring bread with them. Their minds fixed on having no bread, they took Jesus' warning about the leaven of the Pharisees and Sadducees as if it were a warning about literal bread. Jesus recalled to them the two miraculous feedings to show that they had no reason to be anxious about food. The warning about leaven was to be understood not of bread but of the teaching of the Pharisees and Sadducees.
