²Suddenly^[a] a sound^[b] like a violent wind blowing^[c] came from heaven^[d] and filled the entire house where they were sitting.

Acts 2:2 tn Here καί (kai) has not been translated for stylistic reasons. It occurs as part of the formula καὶ ἐγένετο (kai egeneto) which is often left untranslated in Luke-Acts because it is redundant in contemporary English. Here it is possible (and indeed necessary) to translate ἐγένετο as “came” so that the initial clause of the English translation contains a verb; nevertheless the translation of the conjunction καί is not necessary.
Acts 2:2 tn Or “a noise.”
Acts 2:2 tn While φέρω (pherō) generally refers to movement from one place to another with the possible implication of causing the movement of other objects, in Acts 2:2 φέρομαι (pheromai) should probably be understood in a more idiomatic sense of “blowing” since it is combined with the noun for wind (πνοή, pnoē).
Acts 2:2 tn Or “from the sky.” The Greek word οὐρανός (ouranos) may be translated “sky” or “heaven” depending on the context.
