Bitter As Gall

Proverbs 5:3-5 NIV
For the lips of the adulterous woman drip honey,
and her speech is smoother than oil;
4 but in the end she is bitter as gall,
sharp as a double- edged sword.
5 Her feet go down to death;
her steps lead straight to the grave.

The wicked woman in Revelation, Babylon by name, signifies the disobedience and rebellion that leads to destruction. It is a bitter cup, like that which was given our Lord on the cross.

Revelation 8:11 NIV
the name of the star is Wormwood. A third of the waters turned bitter, and many people died from the waters that had become bitter.

The waters of the earth turn bitter from that fallen star Wormwood. Death results, except for the one who accepts the life of Christ.
Enter the ark before the waters rise and time is gone.
