{Conceived} (sunelaben). Luke uses this word eleven times
and it occurs only five other times in the N.T. It is a very old
and common Greek word. He alone in the N.T. has it for conceiving
offspring ( 1:24,31,36  2:21 ) though  Jas 1:15  uses it of lust
producing sin. Hobart (_Medical Language of Luke_, p. 91)
observes that Luke has almost as many words for pregnancy and
barrenness as Hippocrates (en gastri echein,  21:23 ; egkuos,
 2:5 ; steira,  1:7 ; ateknos,  20:28 ). {Hid}
(periekruben). Only here in the N.T., but in late _Koin(825f)
writers. Usually considered second aorist active indicative from
perikrupt(935c), though it may be the imperfect indicative of a late
form perikrub(935c). If it is aorist it is the constative aorist.
The preposition peri makes it mean completely (on all sides)
hid.
