Acts 13:41

Ye despisers (oi katapronhtai). Not in the Hebrew, but in the LXX. It is pertinent for Paul's purpose. Perish (apanisqhte). Or vanish away. First aorist passive imperative. Added by the LXX to the Hebrew. If one declare it unto you (ean ti ekdihghtai umin). Condition of third class with present middle subjunctive, if one keep on outlining (double compound, ek-di-hgeomai) it unto you. Paul has hurled a thunderbolt at the close.
