JMNT(i)
10 Now when He came to be in a more private situation (in accord with ones [who are] alone [though with others]), those [sticking close] around Him – together with the twelve – began questioning Him on the parables (here: obscure illustrations).
11 So He began saying to them, "The secret (mystery; [J. Jeremias: singular, = its present irruption]) of God's kingdom (or: of the sovereign reign of God as King) has been given and so stands as a gift to (or: for; in) you folks; yet to (for; in) those outside, everything (all things; the whole) continues to come to be birthed in parables (= are in obscure, illustrative riddles),
12 "to the end that, 'continuously looking (observing), they may continually look (observe) and yet can (may; should; would) not see so as to perceive, and constantly (or: repeatedly) hearing, they may continually hear, and yet can (may; should; would) not make things flow together so as to comprehend or understand, nor can they at some point turn about (or: unless they turn upon [their path]) and the results (effects) of [their] sins and mistakes should be sent away (set aside; divorced; forgiven) for (or: in) them.'" [Isa. 6:9-10; note: this reading follows synagogue paraphrase, as witnessed in the Peshitta and the Targum, while differing from the Hebrew and LXX – J. Jeremias]
13 He further says to them, "Have you not seen, so as to know and perceive, this parable (obscure illustrative comparison)? (or: You folks have not seen this parable [= Heb. masal: dark saying; riddle].) So how will you folks come to personally know (have intimate and experiential understanding of) all the parables (illustrations, or, riddles)?
