“The LXX offers exegetical help [….] in putting into proper focus the Pharisees’ problem in Luke 18:9-14. Psalm 34:14 (35:13 MT) notes that the purpose of fasting is to assist in humbling the soul and stimulating appropriate prayer. In the prayer that “turns back into the bosom”—the phrase is obscure—we may see a parallel to the utterance of the publican whose words, coming as they did from a head bowed in humility, fell, as it were, into his bosom.
“Hatch and Redpath alert to seven occurrences of the word πίπτειν within the space of five verses in Ezekiel 13. This passage in its context is the best commentary on Matt. 7:24-27. Some in the upper spiritual echelons in Israel misused good intentions in Pharisaism for purposes of moral whitewashing. They sought refuge in their interpretation and hedging of the Torah. But the fortress was to collapse. Jesus’ reiterated ‘You have heard, but I say unto you’ gains significance.”
