A.T. Robertson Commentary Acts 8:39

"And when they came up out of the water, the Spirit of the Lord caught away Philip; and the eunuch saw him no more, for he went on his way rejoicing." — Acts 8:39 (ASV)

Out of the water (εκ του υδατος). Not from the edge of the water, but up out of the water as in Mr 1:10.

Caught away (ηρπασεν). Suddenly and miraculously, for αρπαζω, like the Latin rapio, means to carry off. Cf. 2 Corinthians 12:2; 1 Thessalonians 4:17.

Went on his way (επορευετο). Kept on going, imperfect active.
