Revelation 13:13

That he should even make fire come down out of heaven (ina kai pur poih ek tou ouranou katabainein). Purpose clause again with ina and the present active subjunctive of poiew and the object infinitive of katabainw after poiei. Christ promised great signs to the disciples ( John 14:12 ), but he also warned them against false prophets and false christs with their signs and wonders ( Mark 13:22 ). So also Paul had pictured the power of the man of sin ( 2 Thessalonians 2:9 ). Elijah had called down fire from heaven ( 1 Kings 18:38 ; 2 Kings 1:10 ) and James and John had once even urged Jesus to do this miracle ( Luke 9:54 ).
