5 What, then (or: So then, what), is Apollos? And what is Paul? [They are] attending servants and dispensers of [spiritual] provisions, through whom you folks came to believe and trust – even as the Lord [= Christ or Yahweh] gave (or: gives) to and in each one.
6 I myself plant (or: planted), Apollos irrigated (or: waters; caused [you] to drink), but then God was causing [it/you] to progressively grow up and increase (be augmented).
