Contradiction with Proverbs 3:5
This verse advises trusting in the Lord with all one's heart and not relying on one's own understanding, whereas Psalms 143:10 seeks to be taught to do God's will, implying human efforts in understanding God's will.
Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Contradiction with Jeremiah 10:23
This verse asserts that a man's way is not in himself and it is not in man to direct his steps, potentially conflicting with the plea in Psalms 143:10 for personal guidance in doing God's will, implying an expectation of some autonomous capability to act on God's will.
Jeremiah 10:23: O LORD, I know that the way of man [is] not in himself: [it is] not in man that walketh to direct his steps.
