According to Luke 24:47. Jesus says "it is written" that "...repentance and remission of sins should be preached in his name"
Where, in the Old Testament, the allusion that specifically mentions "repentance and remission of sins" and about them being preached?
Luke 24:45-48 (KJV):
45 Then opened he their understanding, that they might understand the scriptures,
46 And said unto them, Thus it is written, and thus it behooved Christ to suffer, and to rise from the dead the third day:
47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
48 And ye are witnesses of these things.
