"Maher-shalal-hash-baz" was the second prophetic name mentioned in Isaiah chapter 8[1] –9.
The name is mentioned twice in the Hebrew Bible, both times in the Book of Isaiah chapter 8:[2]
Moreover the said unto me, Take thee a great roll and write in it with a man's pen concerning Mahershalalhashbaz.[3]
And I went unto the prophetess; and she conceived and bore a son. Then said the to me, Call his name Mahershalalhashbaz.[4]
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 phrases maher-shalal and hash-baz are synonymous, both meaning approximately "quickly to the plunder". 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).
| ma-hēr | hurry or quickly | ||
| šā-lāl | loot, spoils, booty | ||
| ḥāš | he hurries or he hurried | ||
| baz | prey, spoils |
This is often counted the longest name (and word) used in the Bible, though a possible longer name-phrase in Isaiah is found in Isaiah 9:5 "called Pele-joez-el-gibbor-abi-ad-sar-shalom"[5] [6]
The section is also quoted in the Book of Mormon.[7]
