We can see the painting is divided into half: night on the left and day on the right.   On the night side, a bird of prey flies under the heavens, watching the pestilence attack a group of people in a landscape of ruins. On the day side, archers are shooting a steady stream of arrows down as a city burns.

The good man is surrounded by six angels arranged in a hexagon. If you look at the heads and arms of the angels, you can make out a Star of David, a powerful Kabalistic symbol. On the bottom of the picture you can see a serpent and a lion. The verse goes as follows:

"For he will give His angels charge over thee, To keep thee in His ways. They shall bear thee upon their hands, Lest thou dash thy foot against a stone. Thou shall tread upon the lion and asp; The young lion and the serpent, Thou shall trample under foot."

According to the Kabbalists, the asp or serpent represents sexuality and lust, and the lion, the king of the beasts, represents power. Therefore the good man is rising to a higher realm away from the temptations of lust and power to which many fall. This interpretation was given to me by a woman who studied Kabbalah in Israel.

Psalm 62 ("Only for God wait thou in stillness, my soul") and Psalm 18 ("For thou dost light my lamp, The Lord God dost lighten my darkness") also contain mystical verses and can be used in meditation.
