Contradiction with Proverbs 21:31
This verse contradicts by emphasizing that safety comes from the Lord, while 1 Samuel 17:20 depicts David depending on his own preparations and actions.
Proverbs 21:31: The horse [is] prepared against the day of battle: but safety [is] of the LORD. [safety: or, victory]
Contradiction with Matthew 6:34
This verse advises against worrying about tomorrow, contrasting with David's proactive behavior in 1 Samuel 17:20 as he prepares for the battle.
Matthew 6:34: Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day [is] the evil thereof.
Contradiction with Exodus 14:14
Here, the Lord promises to fight for the Israelites, which contradicts David's initiative to take matters into his own hand in 1 Samuel 17:20.
Exodus 14:14: The LORD shall fight for you, and ye shall hold your peace.
Contradiction with 2 Chronicles 20:15
This verse states that the battle is the Lord's, contrasting with David's active engagement in the battle preparations described in 1 Samuel 17:20.
2 Chronicles 20:15: And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, Thus saith the LORD unto you, Be not afraid nor dismayed by reason of this great multitude; for the battle [is] not yours, but God's.
Contradiction with Psalm 46:10
Contradicts 1 Samuel 17:20 by urging believers to be still and know God is in control, unlike David's active preparation for battle.
Psalm 46:10: Be still, and know that I [am] God: I will be exalted among the heathen, I will be exalted in the earth.
