And when I come, whomsoever ye shall approve by your {c} letters, them will I send to bring your liberality unto Jerusalem.

(c) Which you will give to them to carry.

People's New Testament

16:3 Whomsoever ye shall approve by your letters. The church should select its own messengers, giving them letters as credentials. He lets the Corinthians choose the bearers of their own bounty.

King James Translators' Notes

liberality: Gr. gift

Jamieson-Fausset-Brown Bible Commentary

3. approve by your letters-rather translate, "Whomsoever ye shall approve, them will I send with letters": namely, letters to several persons at Jerusalem, which would be their credentials. There could be no need of letters from them before Paul's coming, if the persons recommended were not to be sent off before it. Literally, "by letters"; an abbreviated expression for "I will send, recommending them by letters" [Grotius]. If English Version be retained, the sense will be, "When I come, I will send those whom by your letters, then to be given them, ye shall approve." But the antithesis (opposition or contrast) to Paul himself (1Co 16:4) favors Grotius' view. So "by" means with (Ro 2:27); and the Greek for "by" is translated, with (2Co 2:4).

liberality-literally, gracious or free gift (2Co 8:4).

Matthew Henry's Concise Commentary

16:1-9 The good examples of other Christians and churches should rouse us. It is good to lay up in store for good uses. Those who are rich in this world, should be rich in good works, 1Ti 6:17,18. The diligent hand will not make rich, without the Divine blessing, Pr 10:4,22. And what more proper to stir us up to charity to the people and children of God, than to look at all we have as his gift? Works of mercy are real fruits of true love to God, and are therefore proper services on his own day. Ministers are doing their proper business, when putting forward, or helping works of charity. The heart of a Christian minister must be towards the people among whom he has laboured long, and with success. All our purposes must be made with submission to the Divine providence, Jas 4:15. Adversaries and opposition do not break the spirits of faithful and successful ministers, but warm their zeal, and inspire them with fresh courage. A faithful minister is more discouraged by the hardness of his hearers' hearts, and the backslidings of professors, than by the enemies' attempts.
