Matt 13:24-30
"God's kingdom is like a farmer who planted good seed in his field. 25 That night, while his hired men were asleep, his enemy sowed thistles all through the wheat and slipped away before dawn. 26 When the first green shoots appeared and the grain began to form, the thistles showed up, too.
27 "The farmhands came to the farmer and said, 'Master, that was clean seed you planted, wasn't it? Where did these thistles come from?'
28 "He answered, 'Some enemy did this.'
"The farmhands asked, 'Should we weed out the thistles?'
29 "He said, 'No, if you weed the thistles, you'll pull up the wheat, too. 30 Let them grow together until harvest time. Then I'll instruct the harvesters to pull up the thistles and tie them in bundles for the fire, then gather the wheat and put it in the barn.'"
