What are Tares?

In Matthew 13:24-25 Jesus said, “The kingdom of heaven is like a man who sowed good seed in his field; but while men slept, his enemy came and sowed tares among the wheat and went his way.” The weed was probably darnel, called cockle and false wheat. It exists worldwide, looking similar to wheat until maturity. Wheat ears are heavy. It hangs down. Darnel ears are light. It stands tall. The wicked seem to prosper while the righteous suffer. Cockle has a deeper root. Removing it would pull out the wheat. A solution is to let both grow together until harvest and separate them then, when the righteous will shine.
