As it is not possible for the army of heaven to be numbered, or the sand of the sea measured, so will I make the seed of my servant David, and the Levites my servants.

How is it possible for it to be quiet, seeing that the Lord has given it orders? against Ashkelon and against the sea-land he has given it directions.

Sudden is the downfall of Babylon and her destruction: make cries of grief for her; take sweet oil for her pain, if it is possible for her to be made well.
