Contradiction with Jeremiah 23:28
Contradicts as it differentiates between profitable and worthless visions, unlike the good and bad in Matthew 13:26.
Jeremiah 23:28: The prophet that hath a dream, let him tell a dream; and he that hath my word, let him speak my word faithfully. What [is] the chaff to the wheat? saith the LORD. [that hath a dream: Heb. with whom is, etc]
Contradiction with Isaiah 5:20
Contrasts clear definitions of good and evil with the indistinguishable plants in Matthew 13:26.
Isaiah 5:20: Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter! [call...: Heb. say concerning evil, It is good, etc]
Contradiction with Luke 6:44
Emphasizes identification of a tree by its fruit, opposing the hidden discernment in Matthew 13:26.
Luke 6:44: For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes. [grapes: Gr. a grape]
Contradiction with Matthew 5:45
Illustrates God's impartial blessings, unlike the separation based on value in Matthew 13:26.
Matthew 5:45: That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
