In Isaiah 9, “Abi-ad” is usually understood as a Hebrew title meaning “Everlasting Father” or “Father of Eternity”. It appears in the prophecy about the coming ruler in Isaiah 9:6, alongside titles like “Wonderful Counselor,” “Mighty God,” and “Prince of Peace”.

What it means

  • The Hebrew form is often explained as a compound of ab (“father”) and ad (“eternity,” “forever”).
  • Many Bible references treat it as a description of the Messiah’s eternal care and rule, not a claim about ordinary human fatherhood.
  • Some interpreters emphasize the phrase as “Father of Eternity,” meaning the one who possesses or gives eternal life and enduring authority.

Why people ask about it

The phrase comes up in Christian discussions because Isaiah 9:6 is a major messianic verse, and different groups debate how to understand the title theologically. In short, “Abi-ad” is not a separate person or mysterious code—it is a Hebrew title linked to Isaiah’s description of the coming king.

Simple version

If you saw “abi ad” in Isaiah 9, it most likely means the Eternal Father / Father of Eternity in the messianic title of Isaiah 9:6.
