Maher-shalal-hash-baz (/ˌmeɪhər ʃælæl ˈhæʃ bɑːz/;Hebrew: מַהֵר שָׁלָל חָשׁ בַּז – "Hurry to the spoils!" or "He has made haste to the plunder!" – was the second mentioned prophetic-name child in Isaiah chapter 7-9.
And I went unto the prophetess; and she conceived, and bore a son. {S} Then said the LORD unto me: 'Call his name Maher-shalal-hashbaz'
The prophet Isaiah's first son Shearjashub is mentioned only once in Isaiah 7:3. Commentators, Jewish and Christian, traditionally note that this first son's name is also prophetic – meaning "the remnant shall return" – but no account of why, when or how this son was named is given in the Book of Isaiah.
The child Maher-shalal-hash-baz is the second prophetic-name child after the birth of Immanuel – traditionally understood as the son of Abi the bride of king Ahaz, i.e., the future king Hezekiah, by many Jewish commentators, or of another woman. The name Maher-shalal-hash-baz is a reference to the impending plunder of Samaria and Damascus by the king of Assyria, Tiglath-Pileser III (734-732 BCE).
