Contradiction with Psalm 91:11
This verse promises God's protection by His angels, whereas Genesis 4:14 describes Cain's fear of being killed without divine protection.
Psalm 91:11: For he shall give his angels charge over thee, to keep thee in all thy ways.
Contradiction with Proverbs 18:10
This verse states that the name of the Lord is a strong tower and the righteous are safe, contradicting the sense of vulnerability stated by Cain in Genesis 4:14.
Proverbs 18:10: The name of the LORD [is] a strong tower: the righteous runneth into it, and is safe. [safe: Heb. set aloft]
Contradiction with Hebrews 13:5
In this verse, God promises never to leave nor forsake His followers, contrasting with Cain's lament about being hidden from God's presence in Genesis 4:14.
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 Matthew 28:20
Jesus' assurance of His continuous presence ('I am with you always') contrasts with Cain's fear of being cast away from God's presence in Genesis 4:14.
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.
Paradox #1
Genesis 4:14 raises a question about how Cain fears being killed by others, even though, according to the timeline, there shouldn't be many people on Earth yet. This can seem inconsistent because the early chapters of Genesis suggest there were only a few individuals alive at that time. This raises questions about who Cain was afraid of encountering.
Paradox #2
In Genesis 4:14, Cain expresses fear of being killed by others, even though the Bible had not yet mentioned other people beyond Adam, Eve, and their immediate family. This raises questions about where these other people came from, leading to contradictions about the population at that time.
Paradox #3
Genesis 4:14 describes Cain expressing concern about being killed by others after being banished. The potential conflict some might see here is the implication of the existence of other humans who could harm Cain, despite only Adam, Eve, Cain, and Abel being mentioned in the story up to that point. This raises questions about where these other people came from if all humans supposedly descended directly from Adam and Eve.
Paradox #4
Genesis 4:14 mentions Cain's concern about being killed after being punished for killing Abel. The contradiction here might be seen in that Cain, who took his brother's life, is worried about his own life being taken in retaliation, highlighting a conflict between the justice he fears and his own lack of mercy. This can be seen as inconsistent since Cain desires protection after having shown violence towards another.
