But that night as everyone slept, his enemy came and planted weeds among the wheat.
When the crop began to grow and produce grain, the weeds also grew.
The farmer's servants came and told him, 'Sir, the field where you planted that good seed is full of weeds!'
"'An enemy has done it!' the farmer exclaimed."'Shall we pull out the weeds?' they asked.
"He replied, 'No, you'll hurt the wheat if you do.
Let both grow together until the harvest. Then I will tell the harvesters to sort out the weeds and burn them and to put the wheat in the barn.'"
Here is another illustration Jesus used: "The Kingdom of Heaven is like a mustard seed planted in a field.
It is the smallest of all seeds, but it becomes the largest of garden plants and grows into a tree where birds can come and find shelter in its branches."
Jesus also used this illustration: "The Kingdom of Heaven is like yeast used by a woman making bread. Even though she used a large amount of flour, the yeast permeated every part of the dough."

Jesus always used stories and illustrations like these when speaking to the crowds. In fact, he never spoke to them without using such parables.
This fulfilled the prophecy that said, "I will speak to you in parables. I will explain mysteries hidden since the creation of the world."
