We know very little of Haggith, but she was probably a dancing girl who
made her way to the front by her ambition and beauty. From her and
from his father we may assume that Adonijah inherited a tendency to
ambition and self-conceit such as Absalom inherited from the union of
David with Bathsheba. It is one of the laws of life that "like

his birthright for a mess of pottage, Rebekah, who, like her brother
Laban is shrewd and cunning, sees her tendency repeated in her son
Jacob, who needed a life of discipline and prayer to set him free from
