*267). 'Goodly loan' signifies whatever one gives to another person selflessly, and from absolutely pure motives. God describes whatever man spends in this manner as a loan made to none other than Him, and He undertakes to repay that loan and to repay it several-fold. The stipulation, however. is that the loan should be a 'goodly' one; that is, it should not he tainted with selfish designs and should be given for the sake of God, to be spent for purposes pleasing to Him
