and the frog asks "Why?" Then the scorpion says, "Because 'it's my nature". These still can repent to our Father and come to Christ, so don't think they're all doomed to hell as of yet. There's still time left. Just like the 'bully' down the street; if he gets out of line with you, he might need a good whipping to help bring him back, and he's to be treated as the 'prodigal son' if he repents and is trying to be a good Christian. That's how God looks even at the Kenite who 'returns' to Him, and we should also.
     That's the end of Cain's genealogy.

 

Gen 4:25   And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.
26    And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD.

     Here starts the genealogy of 'the man Adam', the 'eth Ha' adham' placed in the Garden of Eden to till the soil. 'Seth' means 'substitute' in the Hebrew (Strong's no.8352), which means a replacement for Abel, whom Cain murdered.
     'Enos' is 'Enowsh' in the Hebrew, meaning 'mortal man' (Strong's nos. 583 & 582). At this time 'began men to call upon the name of the LORD'. The word 'began' is 'chalal' in the Hebrew, and it reveals just what this act was. It means 'figuratively, to profane' (Strong's no. 2490). So this means that 'men began to profane the calling upon the name of the LORD'. How might that be done? It would be accomplished by worshipping others gods, such as Baal, replacing the worship of The One True God Jehovah. The King James translators gave a bad translation of 'chalal' because its' Hebrew root ('chalah'= sickly, frail) doesn't fit the context and subject of this verse. A second witness in The Word for this 'profaning' of God's Name, is that Abel did properly worship our Father long before this event here in Gen.4:26 began to take place. However, that Hebrew root 'chalah' does point back to the name 'Enos'.

Genesis 5: the man Adam's Genealogy

 

Gen 5:1   This is THE BOOK OF THE GENERATIONS OF ADAM. In the day that God created man, in the likeness of God made He him;

     This is the start of the generations of the 'eth Ha' adham', i.e., 'the particular man Adam', whom God placed in the Garden of Eden to till the soil, as pointed out in Gen.2:7-8. This first 'ADAM' of Gen.5 is given as a proper name, meaning 'the Adam', i.e., 'Mr. Adam', not mankind. But this particular 'the Adam' 'eth Ha' adham' was slated to be the bloodline which Jesus Christ would be born from.

Gen 5:2    Male and female created He them; and blessed them, and called their name Adam, in the day when they were created.

     This verse is referring back to Gen.1:26, where there is no 'article' in front of 'adam' in the Hebrew manuscripts and means 'mankind in general' without the article. This word 'Adam' here in the KJV is really 'adam' in the Hebrew, aw-dawm, ruddy, i.e. a human being, ( an individual or the species., mankind, etc) (Strong's no.120), not a proper name, in contrast to the previous verse with 'ADAM'. It was mistranslated by the KJV translators. Use your Strong's to compare, and also the Massorah if available to you.
     Basically the first verse is talking about 'the Adam', the 'eth' Ha' adham'. The second verse with the phrase 'Male and female created He them;' is about the sixth day creation of 'general mankind', i.e., the various races of man, 'adam' without the article and particle.
