As in the former verse the apostle had asserted God's sufficiency to repay them what they should lend him. So he here asserteth God's readiness and willingness. This he confirmeth from a promise taken out of Psalms 112:9, where also is further added, his horn shall be exalted with honour. Concerning the merciful man, it is true that Solomon saith, Proverbs 11:24: There is that scattereth, and yet increaseth. The psalmist saith: His righteousness endureth for ever: by which term some understand his bounty or liberality: I had rather understand by it here his obedience to the command of God ht his free distribution to the poor; this remaineth in God's book of remembrance for ever, God will not forget this labour of love, Hebrews 6:10. The friends which he maketh with his mammon of righteousness, shall receive him into everlasting habitations, Luke 16:9. A man's riches cannot remain for ever, but his righteousness, in the distribution of them according to the command of God, that shall remain for ever.
