Acts 3:24

Samuel announced that David would replace Saul (1 Samuel 13:14; 1 Samuel 15:28; 1 Samuel 28:17; cf. 1 Samuel 16:13), but we have no record that he ever gave an explicitly messianic prophecy. Peter seems to have meant that in announcing David’s reign Samuel was also anticipating Messiah’s reign. The other prophets Peter apparently had in mind were all those who spoke of David’s continuing dynastic rule. Peter’s statement in this verse, by the way, shows that Joshua did not fulfill Moses’ prophecy about the coming prophet.
