Abimelech

my father a king, or father of a king, a common name of the
Philistine kings, as "Pharaoh" was of the Egyptian kings. (1.)
The Philistine king of Gerar in the time of Abraham (Gen.
20:1-18). By an interposition of Providence, Sarah was delivered
from his harem, and was restored to her husband Abraham. As a
mark of respect he gave to Abraham valuable gifts, and offered
him a settlement in any part of his country; while at the same
time he delicately and yet severely rebuked him for having
practised a deception upon him in pretending that Sarah was only
his sister. Among the gifts presented by the king were a
thousand pieces of silver as a "covering of the eyes" for Sarah;
i.e., either as an atoning gift and a testimony of her innocence
in the sight of all, or rather for the purpose of procuring a
veil for Sarah to conceal her beauty, and thus as a reproof to
her for not having worn a veil which, as a married woman, she
ought to have done. A few years after this Abimelech visited
Abraham, who had removed southward beyond his territory, and
there entered into a league of peace and friendship with him.
This league was the first of which we have any record. It was
confirmed by a mutual oath at Beersheba (Gen. 21:22-34).

(2.) A king of Gerar in the time of Isaac, probably the son of
the preceeding (Gen. 26:1-22). Isaac sought refuge in his
territory during a famine, and there he acted a part with
reference to his wife Rebekah similar to that of his father
Abraham with reference to Sarah. Abimelech rebuked him for the
deception, which he accidentally discovered. Isaac settled for a
while here, and prospered. Abimelech desired him, however, to
leave his territory, which Isaac did. Abimelech afterwards
visited him when he was encamped at Beersheba, and expressed a
desire to renew the covenant which had been entered into between
their fathers (Gen. 26:26-31).

(3.) A son of Gideon (Judg. 9:1), who was proclaimed king
after the death of his father (Judg. 8:33-9:6). One of his first
acts was to murder his brothers, seventy in number, "on one
stone," at Ophrah. Only one named Jotham escaped. He was an
unprincipled, ambitious ruler, often engaged in war with his own
subjects. When engaged in reducing the town of Thebez, which had
revolted, he was struck mortally on his head by a mill-stone,
thrown by the hand of a woman from the wall above. Perceiving
that the wound was mortal, he desired his armour-bearer to
thrust him through with his sword, that it might not be said he
had perished by the hand of a woman (Judg. 9:50-57).

(4.) The son of Abiathar, and high priest in the time of David
(1 Chr. 18:16). In the parallel passage, 2 Sam. 8:17, we have
the name Ahimelech, and Abiathar, the son of Ahimelech. This
most authorities consider the more correct reading. (5.) Achish,
king of Gath, in the title of Ps. 34. (Compare 1 Sam. 21:10-15.)
