Jesus teaches by the sea. The parables of the sower. Parables are not obvious to everyone – Jesus quotes Isaiah, about those who see but do not perceive. Jesus interprets the parable of the sower. Lamps are not to be put under beds or baskets. Whoever has, to him more will be given; but whoever does not have, even what he has will be taken away from him. The parable of the growing seed: the farmer plants the seed, but another power makes it grow. Parable of the mustard seed, which goes from something very small to something very big. Jesus rebukes the waves in a boat.
