Robertson's NT Word Studies
22:55 {When they had kindled a fire} (periayantwn pur). Genitive absolute, first aorist active participle of periaptw, an old verb, but here only in the N.T. Kindle around, make a good fire that blazes all over. It was April and cool at night. The servants made the fire. {And had sat down together} (kai sunkaqisantwn). Genitive absolute again. Note sun- (together), all had taken seats around the fire. {Peter sat in the midst of them} (ekaqeto ho petros mesos autwn). Imperfect tense, he was sitting, and note mesos, nominative predicate adjective with the genitive, like #Joh 1:26, good Greek idiom.
