1 Corinthians 3:6

I planted

(εγω εφυτευσα). First aorist active indicative of old verb φυτευω. This Paul did as Luke tells us in Acts 18:1-18.Apollos watered

(Απολλως εποτισεν). Apollos irrigated the church there as is seen in Acts 18:24-19. Another aorist tense as in verse 1 Corinthians 3:2.But God gave the increase

(αλλα ο θεος ηυξανεν). Imperfect tense here (active indicative) for the continuous blessing of God both on the work of Paul and Apollos, co-labourers with God in God's field (verse 1 Corinthians 3:9). Reports of revivals sometimes give the glory to the evangelist or to both evangelist and pastor. Paul gives it all to God. He and Apollos cooperated as successive pastors.
