Everlasting Father (KJV, NIV) is one of the four names of the Messiah Child promised by God in Isaiah. The other names are Prince of peace (Sar shalom), Mighty God (’El gibbor) and Wonderful Counselor.
Eternal or Everlasting Father (’Avi‘ad) is a term used for the perpetual head of a family or clan. It is one of several names for God that speaks of His timeless endurance and His fatherly relationship to His people. Earthly fathers often fail or abuse their position. God sets the standard of fatherhood. He is loving and wise; and when he disciplines us, it is for our good.
Everlasting Father in Hebrew:
Strong’s Concordance numbers: 5703, 1 (This name combines the word for eternal or everlasting (‘ad) with that for Father (’avi))
Later in the passage, the word ‘ad appears with its synonym ‘olam as part of the Hebrew expression meaning “forever.”
Bible reference: Isa. 9:6 (In the NASB this name of God is translated “Eternal Father”).
For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, Mighty God,
Everlasting Father [’Avi‘ad], Prince of Peace.
7 Of the greatness of his government and peace
there will be no end.
He will reign on David’s throne
and over his kingdom,
establishing and upholding it
with justice and righteousness
from that time on and forever [ad olam].
The zeal of the Lord Almighty
will accomplish this. (Isaiah 9:6-7 NIV)
The Hebrew word ‘ad does not form part of any other biblical names of God. On the other hand, the Hebrew word ‘olam is part of several names for God: “Our Redeemer from of old,” “Eternal God,” “Everlasting King,” and “Everlasting Rock.”
