A.T. Robertson Commentary Acts 8:15

"who, when they were come down, prayed for them, that they might receive the Holy Spirit:" — Acts 8:15 (ASV)

That they might receive (οπως λαβωσιν). Second aorist active subjunctive of λαμβανω, final clause with οπως. Did they wish the Samaritan Pentecost to prove beyond a doubt that the Samaritans were really converted when they believed? They had been baptized on the assumption that the Holy Spirit had given them new hearts. The coming of the Holy Spirit with obvious signs (cf. 10:44-48) as in Jerusalem would make it plain.
