Contradiction with Jeremiah 17:5
This verse states that trust in man, as opposed to the Lord, brings a curse, which can be seen as a contrast to trusting the divine strength described in Psalms 18:2.
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 Ezekiel 28:2
Here, the declaration of a human who claims to be a god contradicts Psalms 18:2, where it describes the Lord as the true fortress and deliverer, not man.
Ezekiel 28:2: Son of man, say unto the prince of Tyrus, Thus saith the Lord GOD; Because thine heart [is] lifted up, and thou hast said, I [am] a God, I sit [in] the seat of God, in the midst of the seas; yet thou [art] a man, and not God, though thou set thine heart as the heart of God: [midst: Heb. heart]
Contradiction with Psalms 44:6
This verse emphasizes not trusting in human capabilities like weapons for salvation, whereas Psalms 18:2 highlights God as the central source of strength and deliverance.
Psalms 44:6: For I will not trust in my bow, neither shall my sword save me.
Contradiction with Isaiah 31:1
Warns against relying on Egypt for help or strength, in contrast to the reliance on God depicted in Psalms 18:2.
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 Hosea 10:13
Criticizes reliance on one's own way or strength, countering the reliance on God's protection and support found in Psalms 18:2.
Hosea 10:13: Ye have plowed wickedness, ye have reaped iniquity; ye have eaten the fruit of lies: because thou didst trust in thy way, in the multitude of thy mighty men.
