Discovery Box2 Corinthians 3:2-3 
Context3:2 You yourselves are our letter, 1 written on our hearts, known and read by everyone, 3:3 revealing 2 that you are a letter of Christ, delivered by us, 3 written not with ink but by the Spirit of the living God, not on stone tablets 4 but on tablets of human hearts.
1 tn That is, “letter of recommendation.”
2 tn Or “making plain.”
3 tn Grk “cared for by us,” an expression that could refer either to the writing or the delivery of the letter (BDAG 229 s.v. διακονέω 1). Since the following phrase refers to the writing of the letter, and since the previous verse speaks of this “letter” being “written on our [Paul’s and his companions’] hearts” it is more probable that the phrase “cared for by us” refers to the delivery of the letter (in the person of Paul and his companions).
4 sn An allusion to Exod 24:12; 31:18; 34:1; Deut 9:10-11.
