A.T. Robertson Commentary Acts 5:31

"Him did God exalt with his right hand [to be] a Prince and a Saviour, to give repentance to Israel, and remission of sins." — Acts 5:31 (ASV)

Exalt (υψωσεν) In contrast to their murder of Christ as in 2:23f. Peter repeats his charges with increased boldness.

With his right hand (τη δεξια αυτου). So instrumental case, or at his right hand (locative case), or even "to his right hand" (dative case) as in 2:33.

Prince and Saviour (αρχηγον κα σωτηρα). See on 3:15. Clearly "Prince" here.

To give (του δουνα). Genitive of articular infinitive (second aorist active of διδωμ) of purpose.
