'People of Israel' in the Bible

be it known to you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead, in this name does this man stand before you whole.

For truly, against Your holy child Jesus, whom You have anointed, both Herod and Pontius Pilate, with the nations, and the people of Israel, were gathered together

John having before proclaimed the baptism of repentance to all the people of Israel, before His coming.
