Contradiction with Matthew 5:44
While Psalms 35:15 reflects on adversaries' malice, Matthew 5:44 advises loving and praying for enemies, presenting a contrast in attitude towards adversaries.
Matthew 5:44: But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
Contradiction with Proverbs 24:17
Psalms 35:15 describes enemies rejoicing over troubles, but Proverbs 24:17 advises against rejoicing when an enemy falls, thus promoting compassion over schadenfreude.
Proverbs 24:17: Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth:
Contradiction with Romans 12:14
In contrast to the hostility in Psalms 35:15, Romans 12:14 instructs believers to bless those who persecute them, opposing the idea of returning enmity with enmity.
Romans 12:14: Bless them which persecute you: bless, and curse not.
Contradiction with Exodus 23:4-5
Unlike the celebration of misfortune by foes described in Psalms 35:15, Exodus 23:4-5 instructs one to assist even enemies if they are in distress, promoting acts of kindness.
Exodus 23:4-5: If thou meet thine enemy's ox or his ass going astray, thou shalt surely bring it back to him again.
Contradiction with 1 Peter 3:9
Psalms 35:15 describes enemies who do harm, but 1 Peter 3:9 advises not to repay evil for evil, urging instead for blessings and not retaliation.
1 Peter 3:9: Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
Paradox #1
Psalms 35:15 may seem contradictory because it describes people acting joyfully during someone's troubles, which goes against the broader biblical teaching of compassion and support for others in their hardships. This might conflict with the overall message of love and kindness toward others.
