rwp Luke:10:17-19
rwp@Luke:10:17 @{Returned with joy} (\hupestrepsan meta charas\). They had profited by the directions of Jesus. Joy overflows their faces and their words. {Even the demons} (\kai ta daimonia\). This was a real test. The Twelve had been expressly endowed with this power when they were sent out (Luke:9:1|), but the Seventy were only told to heal the sick (10:9|). It was better than they expected. The Gospel worked wonders and they were happy. The demons were merely one sign of the conflict between Christ and Satan. Every preacher has to grapple with demons in his work. {Are subject} (\hupotassetai\). Present passive indicative (repetition).
rwp@Luke:10:18 @{I beheld Satan fallen} (\etheroun ton Satann pesonta\). Imperfect active (I was beholding) and second aorist (constative) active participle of \pipt\ (not {fallen}, \peptkota\, perfect active participle, nor {falling}, \piptonta\, present active participle, but {fall}, \pesonta\). As a flash of lightning out of heaven, quick and startling, so the victory of the Seventy over the demons, the agents of Satan, forecast his downfall and Jesus in vision pictured it as a flash of lightning.
rwp@Luke:10:19 @{And over all the power of the enemy} (\kai epi psan tn dunamin tou echthrou\). This is the heart of "the authority" (\tn exousian\) here given by Jesus which is far beyond their expectations. The victory over demons was one phase of it. The power to tread upon serpents is repeated in strkjv@Mark:16:18| (the Appendix) and exemplified in Paul's case in Malta (Acts:28:3-5|). But protection from physical harm is not the main point in this struggle with Satan "the enemy" (Matthew:13:25; strkjv@Romans:16:20; strkjv@1Peter:5:8|). {Nothing shall in any wise hurt you} (\ouden hums ou m adiksei\). Text has future active indicative, while some MSS. read \adiksi\, aorist active subjunctive of \adike\, common verb from \adikos\ (\a\ privative and \dikos\), to suffer wrong, to do wrong. The triple negative here is very strong. Certainly Jesus does not mean this promise to create presumption or foolhardiness for he repelled the enemy's suggestion on the pinnacle of the temple.
