"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."
References for Matthew 13:35
Then, leaving the crowds outside, Jesus went into the house. His disciples said, "Please explain the story of the weeds in the field."
"All right," he said. "I, the Son of Man, am the farmer who plants the good seed.
The field is the world, and the good seed represents the people of the Kingdom. The weeds are the people who belong to the evil one.
The enemy who planted the weeds among the wheat is the Devil. The harvest is the end of the world, and the harvesters are the angels.
