Proverbs 5:4

² That thou mayest regard discretion, and that thy lips may keep knowledge.

³ For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil:

But her end is bitter as wormwood, sharp as a twoedged sword.

⁵ Her feet go down to death; her steps take hold on hell.

⁶ Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them.

Do read the surrounding verses too, because the context often says more than a single verse.
