ISB ~ 2 Corinthians 8 v2

a wealth of liberality:Paul praises the Macedonians for contributing abundantly to the Jerusalem collection despite their destitute circumstances. He thus challenges the Corinthians, who are comparatively wealthy, to follow the lead of their northern neighbors by giving alms in proportion to their prosperity. These contributions are to be set aside every Sunday when they gather for worship (1 Cor 16:2) (CCC 1351).
