[4:2] 1 sn Though parables can contain a variety of figures of speech (cf. 2:19-22; 3:23-25; 4:3-9, 26-32; 7:15-17; 13:28), many times they are simply stories that attempt to teach spiritual truth (which is unknown to the hearers) by using a comparison with something known to the hearers. In general, parables usually advance a single idea, though there may be many parts and characters in a single parable and subordinate ideas may expand the main idea further. The beauty of using the parable as a teaching device is that it draws the listener into the story, elicits an evaluation, and demands a response.
[2:2] 2 tn Some translations (e.g., NIV, NLT) take the preposition πρός (pro"), which indicates proximity, to mean “outside the door.” Others render it as “in front of the door” (TEV, CEV), and still others, “around the door” (NAB). There is some ambiguity inherent in the description here.
