Abd is Arabic and means a devotee/servant of the God usually.
That word is associated with Black people because Black men for thousands of years were the world wide priests of the temples of Amen, Yahu, Allat, Isis and Diana. Priests were sent from Ethiopia and Kemet to officiate at temples in Nabatae, in far-away Greece, Rome, even France.
Emperor Justin of Rome degraded the importance of the Black priests of Isis when he banned the Nile-Valley/Egyptian mystery and replaced it with Roman Catholicism.
Due to their holiness and zeal for the God and her angels, black men were thus known as Abdullahi, or the servant of Allah. Note that Prophet Mohammed’s grandfather was also an Abd, i.e. Abdul Muttalib.
In Hebrew, the Arabic word Abd is synonymous with Obed. You must remember the biblical book of Obed, the prophet or Obadiah. Well Obed is the same as Abd and here again it is used for a prophet of God.
In Hebrew one says Obed-Yahu, servant of God.
Abd, Obed, are blessed people. Your current day racist inspired mistranslations notwithstanding….
