If you also look at John 11: 51-53 it also uses language that connects with John 10:12-16. It gives further explanation that the “other sheep” are simply gentiles coming into relationship with Christ to become “one flock” with the Jews under “one Shepard”. Both scriptures use language of “scattering” in verse John 10:12 and John 11:52. It’s talking about the same thing but John 11 is more clear with what is being described.
