Sirach 20:30
Ben Sira, Ecclesiasticus27 The wise person advances himself by his words, and one who is sensible pleases the great. 28 Those who cultivate the soil heap up their harvest, and those who please the great atone for injustice. 29 Favors and gifts blind the eyes of the wise; like a muzzle on the mouth they stop reproofs. 30 Hidden wisdom and unseen treasure, of what value is either? 31 Better are those who hide their folly than those who hide their wisdom.
Matthew 13:44
44 “The kingdom of heaven is like a treasure, hidden in a field, that a person found and hid. Then because of joy he went and sold all that he had and bought that field. 45 “Again, the kingdom of heaven is like a merchant searching for fine pearls. 46 When he found a pearl of great value, he went out and sold everything he had and bought it. 47 “Again, the kingdom of heaven is like a net that was cast into the sea that caught all kinds of fish. 48 When it was full, they pulled it ashore, sat down, and put the good fish into containers and threw the bad away. 49 It will be this way at the end of the age. Angels will come and separate the evil from the righteous 50 and throw them into the fiery furnace, where there will be weeping and gnashing of teeth. 51 “Have you understood all these things?” They replied, “Yes.” 52 Then he said to them, “Therefore every expert in the law who has been trained for the kingdom of heaven is like the owner of a house who brings out of his treasure what is new and old.”
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), (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 ..."
