According to Genesis 25:4, Abida (Hebrew: אֲבִידָע ʾĂḇīḏāʿ) was the son of Midian, and the grandson of Abraham and his wife Keturah.
He had four brothers: Ephah, Epher, Hanoch and Eldaah.
[1] According to Easton's Bible Dictionary, Abida means "father of knowledge" or "knowing."
On the basis of his derivation from Midian, Easton infers that he was the ancestor of an Arab tribe.
