Jesus told a parable that compares the kingdom of heaven to a man who sows seeds in his field.
While everyone was sleeping, an enemy came and sowed weeds with the wheat. When the wheat sprouted, so did the weeds.
It was an enemy who did this.
I thought you sowed good seeds. Where did the weeds come from?
They let the weeds grow with the wheat because if they pulled them up they might pull up the wheat too. When the time for harvesting came, the harvesters were to tie the weeds in bundles to be burned. Then gather the wheat and take it to the barn.
