1 sn The expression I planted is generally taken to mean that Paul founded the church at Corinth. Later Apollos had a significant ministry there (watered). See also v. 10.
2 tn Grk “is anything.”
3 tn Although 1 Cor 3:9 is frequently understood to mean, “we are coworkers with God,” such a view assumes that the genitive θεοῦ (qeou) is associative because of its relationship to συνεργοί (sunergoi). However, not only is a genitive of association not required by the syntax (cf. ExSyn 130), but the context is decidedly against it: Paul and Apollos are insignificant compared to the God whom they serve (vv. 5-8).
4 sn The various materials described here, both valuable (gold, silver, precious stones) and worthless (wood, hay, or straw) refer to the quality of work built on the foundation, or possibly to the motivation of those doing the building. The materials themselves have been understood (1) as deeds or (2) as people (since ultimately the passage is addressing those who minister to others).
