Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity; he that ruleth, with diligence; he that sheweth mercy, with cheerfulness.
Or he that exhorteth. Since all preaching-whether by apostles, prophets, or teachers-was followed up by exhortation (Acts 11:23; Acts 14:22; Acts 15:32, etc.), many think that no specific class is here in view. But if liberty was given to others to exercise themselves occasionally in exhorting either the brethren generally or small parties of the less instructed, the reference may be to them.
He that giveth - in the exercise of private benevolence, probably rather than in the discharge of diaconal duty.
[Let him do it] with simplicity, х haploteeti (G572)]. So the word probably means. But, as simplicity seems enjoined in the next clause but one of this same verse, perhaps the meaning here is, 'with liberality,' as the same word is rendered in 2 Corinthians 8:2; 2 Corinthians 9:11.
He that ruleth, х proistamenos (G4291)] - whether in the Church or his own household (see 1 Timothy 3:4-5), where the same word is applied to both,
With diligence, х en (G1722) spoudee (G4710)] - with earnest purpose;
He that showeth mercy, with cheerfulness - not only without grudging either trouble or pecuniary relief, but feeling it to be "more blessed to give than to receive, and to help than be helped.
