Contradiction with Jeremiah 17:5
This verse states, "Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD." It emphasizes the futility of relying on human strength, which can contradict the emphasis on divine help in Psalms 33:20, but only in the sense that the need for human effort is sometimes present, albeit secondary to divine reliance.
Jeremiah 17:5: Thus saith the LORD; Cursed [be] the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.
Contradiction with Matthew 7:7
It states, "Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you." This verse stresses active seeking as opposed to waiting on the Lord, which may be viewed as a contrast to the patient waiting emphasized in Psalms 33:20.
Matthew 7:7: Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
Contradiction with Proverbs 3:5-6
Although this verse encourages trust in the Lord, it emphasizes human understanding not having a role, which could be seen as contrary to the active aspect of "waiting" involving hope and expectation in Psalms 33:20.
Proverbs 3:5-6: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
