KJV:
Let them be confounded that persecute me, but let not me be confounded: let them be dismayed, but let not me be dismayed: bring upon them the day of evil, and destroy them with double destruction.
NASB:
Let those who persecute me be put to shame, but as for me, let me not be put to shame; Let them be dismayed, but let me not be dismayed. Bring on them a day of disaster, And crush them with twofold destruction!
