'Double' in the Bible

First I will recompense their iniquity and their sin double, because they have polluted my land with the carcasses of their detestable things, and have filled my inheritance with their abominations.

Let them be disappointed who persecute me, but let not me be disappointed; let them be dismayed, but don't let me be dismayed; bring on them the day of evil, and destroy them with double destruction.
