1 Enoch 50:2
1 And in those days a change shall take place for the holy and elect, and the light of days shall remain upon them, and glory and honor shall turn to the holy, 2 On the day of affliction when evil shall have been stored up against the sinners. And the righteous shall be victorious in the name of the Lord of Spirits: And He will cause the others to witness this that they may repent and abandon the works of their hands. 3 They shall have no honor through the name of the Lord of Spirits, yet through His name they shall be saved, and the Lord of Spirits will have compassion on them, for His compassion is great.
Tobit 4:9
7 give alms from your possessions, and do not let your eye begrudge the gift when you make it. Do not turn your face away from anyone who is poor, and the face of God will not be turned away from you. 8 If you have many possessions, make your gift from them in proportion; if few, do not be afraid to give according to the little you have. 9 So you will be laying up a good treasure for yourself against the day of necessity. 10 For almsgiving delivers from death and keeps you from going into the Darkness. 11 Indeed, almsgiving, for all who practice it, is an excellent offering in the presence of the Most High.
Notes and References
"... This verse contains the command: 'Habitually store up as treasure for yourselves treasures in heaven.' How would the Matthean Jesus' auditors have understood this? Consider the following: Tobit 4:8-9, regarding giving of one's possessions, says, 'So you will be laying up good treasure for yourself'; Sirach 29:10-12, regarding helping a poor man (verse 9), says, 'Lay up your treasure according to the commandments of the Most High'; 4 Ezra 6:5 - 'before those who stored up treasures of faith were sealed'; 2 Baruch 24:1 - 'the treasuries in which are brought together the righteousness of all, those who have proven themselves to be righteous'; mishnah Peah 1:1 - 'These are things whose fruits a man enjoys in this world while the capital is laid up for him in the world to come: honoring father and mother, deeds of loving kindness, making peace between a man and his fellow; and the study of the Law is equal to them all"; tosefta Peah 4: 18:0 - "My ancestors stored up treasures for this lower world, but I, through giving charity, have stored up treasures for the heavenly world above." (Compare Matthew 19:21; Luke 12:21; Hebrews 11:26.) The treasure that is laid up in heaven is one's generosity toward others. This has permanence. Moth, rust, and thieves cannot touch generosity toward others ..."
