Contradiction with Proverbs 21:31
Ezekiel 17:17 suggests military actions fail without God's help, while Proverbs 21:31 implies preparations for battle are human responsibility, with victory from the Lord.
Proverbs 21:31: The horse [is] prepared against the day of battle: but safety [is] of the LORD. [safety: or, victory]
Contradiction with Jeremiah 17:5
Ezekiel 17:17 discusses failure due to trusting in human help, whereas Jeremiah 17:5 contrasts by cursing trust placed in humans over God.
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 Psalm 20:7
Ezekiel 17:17 indicates a reliance on arms without divine backing fails; Psalm 20:7 contrasts by stating true trust is in the Lord, not chariots or horses.
Psalm 20:7: Some [trust] in chariots, and some in horses: but we will remember the name of the LORD our God.
Contradiction with Isaiah 31:1
Ezekiel 17:17 shows the futility of seeking alliances, similar to Isaiah 31:1, but Isaiah explicitly contrasts trust between Egypt's help and God.
Isaiah 31:1: Woe to them that go down to Egypt for help; and stay on horses, and trust in chariots, because [they are] many; and in horsemen, because they are very strong; but they look not unto the Holy One of Israel, neither seek the LORD!
Contradiction with 1 Samuel 17:47
Ezekiel 17:17 implies military might cannot succeed without God, while 1 Samuel 17:47 shows faith that success comes from God alone and not by sword or spear.
1 Samuel 17:47: And all this assembly shall know that the LORD saveth not with sword and spear: for the battle [is] the LORD'S, and he will give you into our hands.
