Short answer:
So-called Black/Negro/African-American people make up some of the descendants of the ancient Hebrews of Israel. The picture of “Jesus” that is commonly accepted is not accurate and is probably Caesar Bogoria (look it up). The Scriptures and Gospels do not teach Christianity, rather, Christianity mixes pagan traditions and worldly views with the Truth of the Word. Christians, Jewish people, and Muslims all had a hand in the slave trade and the oppression of Hebrews. Christians did the same thing that is done today, part of the Word is used to promote a specific idea and the rest is ignored, to justify and perpetuate slavery in America.
The Hebrews are scattered around the world but those brought to America in ships through the slave trade can be identified by plenty of evidence inside and outside the Word of God. The following will show evidence that the Jewish people are not descendants of the ancient Hebrews of Israel, that the Hebrew slaves are not African, that Hebrews were not Moors or Egyptians, and explain why God chose to do this to His chosen people.
A lot of this is discussed in this video of Sabbath study from 2014 at about 41 minutes into the video:
