Continuing on from my Part 4 post with the Book of Proverbs written by King Solomon the son of King David... Most people have heard of the name 'King Solomon' and quite rightly too. The bible tells us he was at the time (I don't know if it still applies today) the wisest among all men, "And he spake three thousand proverbs: and his songs were a thousand and five."
1 Kings 4:32

Pitfalls of Immorality

3 For the lips of an adulteress drip honey
And smoother than oil is her speech;
4 But in the end she is bitter as wormwood,
Sharp as a two-edged sword.
5 Her feet go down to death,
Her steps take hold of Sheol.
6 She does not ponder the path of life;
Her ways are unstable, she does not know it.
7 Now then, my sons, listen to me
And do not depart from the words of my mouth.
8 Keep your way far from her
And do not go near the door of her house,
9 Or you will give your vigor to others
And your years to the cruel one.
Pro 5:3-9
