🔼The name Ahoah in the Bible
The only person in the Bible who bears the name Ahoah is a son of Bela, the first-born of Benjamin, who is also called Ahijah (1 Chronicles 8:4, compare with 8:7). This Ahoah fathered a tribe, called the Ahohites, and the Ahohites mentioned in the Bible are Dodo, Dodai and Zalmon, who is also known as Ilai.
🔼Etymology of the name Ahoah
The origin of the name Ahoah is unclear and the various sources do not agree. Alfred Jones (Dictionary of Old Testament Proper Names) and BDB Theological Dictionary are quick to assume that the name Ahoah is an alternate form of Ahijah, because the only Ahoah in the Bible is also called Ahijah. The proposition is that the name Ahoah consists of (1) the word אח (ah), meaning brother, and (2) יה (Yah) = יהו (Yahu) = יו (Yu), which is an abbreviated form of the name of the Lord: YHWH. Hence Jones' Dictionary of Old Testament Proper Names translates this name with Brother Of The Lord and BDB Theological Dictionary reads the similar Brother Of Yah.
However, the name Ahoah is spelled with waw-heth and not with waw-he, and that makes a lot of difference. So much even that a relation between the two is far from obvious and not certain at all. In fact, it's really quite doubtful.
The name Ahoah could be constructed from a past tense of the root אחח, and would mean He Howled.
