1 tn The words “the gift itself” are not in the Greek text but are implied. Translators often supply an English phrase like “it is” (NASB) but in the context, Paul is clearly referring to the collection Titus was to oversee (2 Cor 8:4-7). Therefore there is no reason not to specify the referent (the gift) more narrowly for clarity.
2 tn “This” refers to sending the brother mentioned in 2 Cor 8:18 to Corinth along with Titus. The words “We did this” have no equivalent in the Greek text, but are necessary to maintain the thought flow in English. The Greek participle that begins v. 20 continues the sentence begun in v. 18 which concerns the sending of the other brother mentioned there.
