'Double' in the Bible

Let those who persecute me be shamed, but as for me, protect me from shame;Let them lose courage, but let me be undaunted.Bring on them a day of tragedy,And destroy them with double destruction!

“Go against [Babylon] the land of Merathaim (Double Rebellion),Go up against it and against the people of Pekod (Punishment).Kill and utterly destroy them,” says the Lord,“And do everything that I have commanded you.”
