Sirach 31:15Ben Sira, Ecclesiasticus
13 Remember that a greedy eye is a bad thing. What has been created more greedy than the eye? Therefore it sheds tears for any reason. 14 Do not reach out your hand for everything you see, and do not crowd your neighbor at the dish. 15 Judge your neighbor's feelings by your own, and in every matter be thoughtful. 16 Eat what is set before you like a well brought-up person, and do not chew greedily, or you will give offense. 17 Be the first to stop, as befits good manners, and do not be insatiable, or you will give offense. 18 If you are seated among many persons, do not help yourself before they do.
7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened for you. 8 For everyone who asks receives, and the one who seeks finds, and to the one who knocks, the door will be opened. 9 Is there anyone among you who, if his son asks for bread, will give him a stone? 10 Or if he asks for a fish, will give him a snake? 11 If you then, although you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him! 12 In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.
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 ..."
