Contradiction with Matthew 28:20
This verse speaks of Jesus being with us always, which contrasts with the plea in Psalms 90:13 asking for God's return.
Matthew 28:20: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, [even] unto the end of the world. Amen.
Contradiction with Isaiah 41:10
Isaiah emphasizes God's constant presence and help, unlike Psalms 90:13, where there is a request for God to return.
Isaiah 41:10: Fear thou not; for I [am] with thee: be not dismayed; for I [am] thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.
Contradiction with Hebrews 13:5
God's promise to never leave or forsake contradicts Psalms 90:13's implication of God's absence.
Hebrews 13:5: [Let your] conversation [be] without covetousness; [and be] content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
Contradiction with Joshua 1:9
God's assurance of His presence with Joshua conflicts with the plea for return in Psalms 90:13.
Joshua 1:9: Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God [is] with thee whithersoever thou goest.
Contradiction with Deuteronomy 31:6
Promises of God never leaving His people, contrasting the request for return in Psalms 90:13.
Deuteronomy 31:6: Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he [it is] that doth go with thee; he will not fail thee, nor forsake thee.
Paradox #1
Psalms 90:13 asks for compassion and for God to return to His people after being away or angry. The potential contradiction or conflict could be that it portrays a view of God as changing His mind or needing to be persuaded to be compassionate. This might seem inconsistent with the idea of an all-knowing, unchanging deity who is consistently loving and merciful.
