2 Corinthians 8:12-15

For if the eagerness [to give] is there, it is acceptable according to what one has, not according to what he does not have. For it is not [intended] that others be relieved [of their responsibility] and that you be burdened [unfairly], but that there be equality [in sharing the burden]— at this present time your surplus [over necessities] is going to supply their need, so that [at some other time] their surplus may be given to supply your need, that there may be equality; as it is written [in Scripture], “HE WHO gathered MUCH DID NOT HAVE TOO MUCH, AND HE WHO gathered LITTLE DID NOT LACK.” [Ex 16:18]
