Mark 8:14
The disciples had forgotten to bring bread, except for one loaf they had with them in the boat — the one loaf that the disciples have in the boat is the setup for the leaven teaching that follows. The forgetfulness is the disciples' characteristic failure to think ahead — the same disciples who watched Jesus feed thousands twice are now worried about one loaf. The one loaf in the boat will become the ironic context for the warning about the leaven of the Pharisees and Herod.
