“As it is written.
‘He scatters abroad.
He gives to the poor.
καθὼς γέγραπται Ἐσκόρπισεν, ἔδωκεν τοῖς πένησιν, ἡ δικαιοσύνη αὐτοῦ μένει εἰς τὸν αἰῶνα.
Paul said as it is written (καθὼς γέγραπται). “He scatters abroad (Ἐσκόρπισεν). He gives (ἔδωκεν) to the poor (ἔδωκεν τοῖς πένησιν). His righteousness (ἡ δικαιοσύνη αὐτοῦ) endures forever (μένει εἰς τὸν αἰῶνα).” Paul cited Psalm 112:9 to get his point across. “They have distributed freely. They have given to the poor. Their righteousness endures forever. Their horn is exalted in honor.” The righteous are firm and secure in Yahweh so that they are not afraid. They distribute to the poor so that their righteousness endures forever. They will have the horn of plenty as their honor just like a plentiful harvest. By giving to others, their righteousness will last forever. Paul always contrasted the finite present with the eternal future. Will your righteousness endure forever?
