Luke 19:43

ὅτι, for, because, introducing a prophetic picture of coming ruin, either to explain the εἰ ἔγνως = what you would have escaped had you but known; or to substantiate the assertion of judicial blindness = no hope of your seeing now; your fate sealed; judgment days will surely come (ἥξουσιν ἡμέραι). Then follows an awful picture of these judgment days in a series of clauses connected by a fivefold καὶ, the first being = when. The description recalls Isaiah 29:3 so closely that the use of such definite phrases before the event is quite conceivable, although many critics think the prophecy so certainly ex eventu as to use it for fixing the date of the Gospel. χάρακα, a palisade (here only in N.T.). Titus did erect a palisaded mound around Jerusalem, and, after it was destroyed by the Jews in a sortie, he built a wall.
