Why did Jesus want the Apostles to distant themselves from the gentiles? ?

Because it is the right thing to do, that is, to give bread to your children first and then to strangers. At this time the jews had not been rejected yet, and were still considered God�s children. The gentiles had rejected the word of God in the past in order to follow idols, so it was not God�s fault. when the jews finally rejected the Son, then came the adoption of sons with the gentiles for they would be ready to accept Christ.
