And they had forgotten to bring bread and they only had one loaf with them in the boat. Bible other translations

“And they had forgotten to bring bread.” When Jesus and the apostles landed on the east side of the lake the apostles discovered they had forgotten to take food with them. Getting bread on the populated west and northwest side of the lake would have been easy, but not easy on the more deserted east side. So the apostles were concerned about forgetting food and thus misunderstood Jesus when he said to beware of the leaven of the Pharisees, Sadducees, and Herod” (Matt. 16:6; Mark 8:15).

“one loaf.” A “loaf” of the flatbread of the Bible was quite like a pancake, so only one loaf of bread would be like having one pancake for the 12 apostles and Jesus. The only thing the disciples had in the boat was one “loaf” of bread.
