A.T. Robertson Commentary Luke 23:10

"And the chief priests and the scribes stood, vehemently accusing him." — Luke 23:10 (ASV)

Stood (ιστηκεισαν). Second perfect active intransitive of ιστημ with sense of imperfect. They stood by while Herod quizzed Jesus and when he refused to answer, they broke loose with their accusations like a pack of hounds with full voice (ευτονως, adverb from adjective ευτονος, from ευ, well, and τεινω, to stretch, well tuned). Old word, but in the N.T. only here and Ac 18:28.
