Albert Barnes on 2 Corinthians 8:6

Insomuch. The sense of this passage seems to be this: "We were encouraged by this unexpected success among the Macedonians. We were surprised at the extent of their liberality. And encouraged by this, we requested Titus to go among you and finish the collection which you had proposed, and which you had begun. Lest you should be outstripped in liberality by the comparatively poor Macedonian Christians, we were anxious that you should perform what you had promised and contemplated; and we employed Titus, therefore, that he might go at once and finish the collection among you."

The same grace also. Marg., "gift." 2Cor 8:1. The word refers to the contribution which he wished to be made.

(1) "same grace" "gift" (+) "grace also" "liberally"
