A.T. Robertson Commentary 1 Corinthians 3:7

"So then neither is he that planteth anything, neither he that watereth; but God that giveth the increase." — 1 Corinthians 3:7 (ASV)

So then neither--neither--but (Hωστε ουτε--ουτε--αλλ'). Paul applies his logic relentlessly to the facts. He had asked

what (τ) is Apollos or Paul (verse 5). The answer is here.

Neither is anything (τ)

the one who plants nor the one who waters . God is the whole and we are not anything.
