Matthew 11:12
11 “I tell you the truth, among those born of women, no one has arisen greater than John the Baptist. Yet the one who is least in the kingdom of heaven is greater than he is! 12 From the days of John the Baptist until now the kingdom of heaven has suffered violence, and forceful people lay hold of it. 13 For all the prophets and the law prophesied until John appeared. 14 And if you are willing to accept it, he is Elijah, who is to come. 15 The one who has ears had better listen! 16 “To what should I compare this generation? They are like children sitting in the marketplaces who call out to one another, 17 “‘We played the flute for you, yet you did not dance; we wailed in mourning, yet you did not weep.’
Sifre Deuteronomy 49
Halakhic Midrash"and to cleave to Him": How is it possible for a man to ascend the heights and cleave to Him? Is it not written (Ibid. 4:24) "For the L-rd your G-d is a consuming fire"? and (Daniel 8:9) "His throne was like a fiery flame and its wheels like burning fire"? But, (the intent is) cleave to the sages and to the disciples, and I will account it to you as if you had ascended the heights and had taken it (the Torah). And not as if you had taken it peacefully, but as if you had waged war and taken it. And thus is it written (Psalms 68:19) "You ascended on high; you took spoils; you took gifts for man."
Notes and References
"... There are some intriguing features about Matthew’s use of Sirach: Most of these parallels are unique to Matthew among the gospels. Included here are the structuring of the beatitudes (5:3–12), the makarism concerning those who mourn (5:4), the antithesis against adultery (5:27–28), the warning against prayers that use empty phrases (6:7), warnings against laying up treasure on earth (6:19–24), advice about judging good from bad fruit (7:16), the allusions to Elijah (11:14) and (17:11), Jesus’ teaching concerning the heavy yoke (11:28–30), the parable of the treasure hidden in the field (13:44), the warning that the son of man will repay grievances (16:27), and the separation of the sheep and goats (25:34–40). In other words, these texts and themes are singular to the Matthean mindset and thus are not typical of the remaining evangelists. (2) The vast majority of these usages are related to the topic of wisdom and instruction, a theme naturally derived from Sirach that clearly adds to Matthew’s standing as a gospel focused on teachings and contemplative sayings. But these lessons are not simply sapiential in orientation. In many cases they are associated with eschatological concerns, as with those parallels that appear (6:14), (6:20), (11:14), (16:27), #18 (17:11), and (25:34–40). Thus, regardless of whether Jesus of Nazareth was actually concerned for a futuristic eschatology, Matthew finds within the materials of Sirach a working source by which to portray his teachings as such ..."
