In his commentary on Acts, Professor Richard Longenecker makes this comment on Acts 2:25:
"It should be remembered that only Luke among the synoptists omitted the cry of dereliction from the cross: 'My God, my God, why have you forsaken me?' (Matt 27:46; Mark 15:34); and only Luke has included the more filial, final word: 'Father, into your hands I commit my spirit' (Luke 23:46). Both the omission and the inclusion are in line with the quotation of Ps 16:8 here [in Acts 2:25]: 'I saw the Lord always [DIA PANTOS] before me. Because he is at my right hand, I will not be shaken'" (Longenecker 77-78).
