{Laid they their hands} (epetithesan tas cheiras).
Imperfect active, repetition. The laying on of hands did not
occur at the great Pentecost ( 2:4,33 ) nor in  4:31  10:44  nor
is it mentioned in  1Co 12  14 . It is mentioned in  Ac 6:7 
about the deacons and in  13:3  when Barnabas and Saul left
Antioch. And in Saul's case it was Ananias who laid his hands on
him ( 9:17 ). Hence it cannot be concluded that the Holy Spirit
was received only by the laying on of the hands of the apostles
or by the hands of anyone. The so-called practice of
"confirmation" appeals to this passage, but inconclusively. {They
received} (elambanon). Imperfect active, repetition as before
and pari passu with the laying on of the hands.
