'Descendant' in the Bible

concerning His Son, who was born of a descendant of David according to the flesh,

I say then, God has not rejected His people, has He? May it never be! For I too am an Israelite, a descendant of Abraham, of the tribe of Benjamin.

Remember Jesus Christ, risen from the dead, descendant of David, according to my gospel,

For assuredly He does not give help to angels, but He gives help to the descendant of Abraham.
