Jamieson, Fausset and Brown on Acts 13:23-25

23-25. Of this man's seed hath God, according to ... promise, raised unto Israel a Saviour, Jesus--The emphasis on this statement lies: (1) in the seed from which Christ sprang--David's--and the promise to that effect, which was thus fulfilled; (2) on the character in which this promised Christ was given of God--"a Saviour." His personal name "Jesus" is emphatically added, as designed to express that very character. (See on Mt 1:21).
