NET

5 Therefore I thought it necessary to urge these brothers to go to you in advance and to arrange ahead of time the generous contribution you had promised, so this may be ready as a generous gift and not as something you feel forced to do.

Darby

5 I thought it necessary therefore to beg the brethren that they would come to you, and complete beforehand your fore-announced blessing, that this may be ready thus as blessing, and not as got out of you.

KJV

5 Therefore I thought it necessary to exhort the brethren, that they would go before unto you, and make up beforehand your bounty, whereof ye had notice before, that the same might be ready, as [a matter of] bounty, and not as [of] covetousness.
