Sirach 37:2
Ben Sira, Ecclesiasticus1 Every friend says, "I too am a friend"; but some friends are friends only in name. 2 Is it not a sorrow like that for death itself when a dear friend turns into an enemy? 3 O inclination to evil, why were you formed to cover the land with deceit? 4 Some companions rejoice in the happiness of a friend, but in time of trouble they are against him.
Matthew 26:38
36 Then Jesus went with them to a place called Gethsemane, and he said to the disciples, “Sit here while I go over there and pray.” 37 He took with him Peter and the two sons of Zebedee, and he became anguished and distressed. 38 Then he said to them, “My soul is deeply grieved, even to the point of death. Remain here and stay awake with me.” 39 Going a little farther, he threw himself down with his face to the ground and prayed, “My Father, if possible, let this cup pass from me! Yet not what I will, but what you will.” 40 Then he came to the disciples and found them sleeping. He said to Peter, “So, couldn’t you stay awake with me for one hour?
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 ..."
