Albert Barnes Commentary Acts 8:29

"And the Spirit said unto Philip, Go near, and join thyself to this chariot." — Acts 8:29 (ASV)

The Spirit. (See Barnes on Acts 8:26).

The Holy Spirit is here evidently intended. The thought in Philip's mind is here traced to his suggestion. All good thoughts and designs have the same origin.

Join yourself. Join him in his chariot. Go and sit with him.
