Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Contradiction with Matthew 8:26
Jesus chides the disciples for being fearful and having little faith, which contradicts the fear and hesitation expressed by David's men in 1 Samuel 23:3.
Matthew 8:26: And he saith unto them, Why are ye fearful, O ye of little faith? Then he arose, and rebuked the winds and the sea; and there was a great calm.

2 Timothy 1:7: For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
