Matthew 6:4
1 “Be careful not to display your righteousness merely to be seen by people. Otherwise you have no reward with your Father in heaven. 2 Thus whenever you do charitable giving, do not blow a trumpet before you, as the hypocrites do in synagogues and on streets so that people will praise them. I tell you the truth, they have their reward! 3 But when you do your giving, do not let your left hand know what your right hand is doing, 4 so that your gift may be in secret. And your Father, who sees in secret, will reward you. 5 “Whenever you pray, do not be like the hypocrites because they love to pray while standing in synagogues and on street corners so that people can see them. Truly I say to you, they have their reward! 6 But whenever you pray, go into your inner room, close the door, and pray to your Father in secret. And your Father, who sees in secret, will reward you.
2 Enoch 51:4
Secrets of Enoch1 Extend your hands to the poor as much as you can. 2 Do not hide your wealth in the earth. 3 Assist the faithful in times of distress, and distress will not find you in your time of trouble. 4 Bear every grievous and cruel burden that comes upon you for the sake of the Lord, and you will find your reward on the day of judgment. 5 It is good to visit the Lord's dwelling in the morning, midday, and evening, to honor your Creator. 6 Every living thing glorifies Him, and every visible and invisible creature praises Him.
Notes and References
"... Enoch forbids his children to swear oaths, but rather they should say “Yes Yes” or “No, No” (Chapter 49). This is obviously similar to the teaching of Jesus in Matthew 5:34-37. As in the Gospels, the emphasis in 2 Enoch is on telling the truth in the first place. This is the most obvious of several links to the Sermon on the Mount in this section of 2 Enoch. There are significant differences as well. In chapter 53 Enoch warns his children not to rely on the fact their father is in heaven (“do no say, “our father is in heaven”) while the Lord’s Prayer begins by addressing God directly as father. Likely Jesus is working through the same common stock of rabbinical ethical teachings in the Sermon on the Mount which the author of 2 Enoch has in mind. It is also possible 2 Enoch is influenced by Matthew. The difference is the increased internalization of the commands of God found in Matthew 5-7. Murder is bad, but hatred and anger are worse. Adultery is bad, but lust is worse. This “internalized ethic” is missing from 2 Enoch ... Compare Treasures in Heaven/Alms (2 Enoch 51, Matthew 6:1-4; 19-24) ..."
