What were the years of their migration?
All motown acts were subjected to "charm school" to help singers develop proper etiquette of performing on stage, presenting themselves in front of the public and how to talk to the media.
Many of these singers came from poor backgrounds and had a rough upbringing. For example, the Jackson 5 did not know much about city life, business or popular music in general.
They had to be taught the 'social graces' which many of their audiences expected from them and loved them for.
There were certain things they had to wear, certain things they could not say and certain mannerism they had to adopt to project a popular and likeable image.

It is an interesting question but it is necessary to contextualize it.
First of all, hebrew is any member of ancient northern semitic people that were ancestors of the Jews, this definition is according Britannica Book.
But if I Have to mention the Bible the Hebrews was the Town of God defined in the Antique Testament and they had roles and commandments from God to follow. They had a sacerdote or lead who always talked with God and after communicated the messages for the People. One different from the people around them was that they can not eat murder animals and don't get idols of wood or someone else.
Now if we does check the new testament, the hebrews just believed in the Law of Moses and it was very different of pharisees, sadducees and son of them didn't believe in Jesus Christ.
Nowadays these different of doctrine about God are alive and they have produced serious conflict between nations and people.
