Contradiction with Jeremiah 17:5
This verse emphasizes the futility of trusting in man, whereas Psalm 71:1 emphasizes trust in divine protection, suggesting that trust should be in God rather than humans.
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 Proverbs 28:26
While Psalms 71:1 advocates trusting in God's protection, Proverbs 28:26 warns against trusting one's own heart, which can imply the frailty of personal judgment and the need for divine guidance.
Proverbs 28:26: He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
