🔼The name Zererath in the Bible
The name Zererath (some translations insist on Zererah) occurs only once in the Bible. When Gideon and his three hundred hooters caused the Midianites to run for their lives, they ran as far as Beth-shittah toward Zererath (Judges 7:22).
Because the Hebrew letter ר (resh) is somewhat similar in appearance to the letter ד (daleth), many scholars assume a text error and Zererath (צררת) is actually Zererah (צררה), and thus the same as Zeredah (צרדה). Zeredah is mentioned by the Chronicler as the place where Huram-abi worked his metallurgy in service of king Solomon (2 Chronicles 4:17). And since the author of Kings mentions the same endeavor, but has Hiram work in Zarethan (צרתן), many scholars go on assuming that all three names cover the same place.
Although there may be many academic benefits to the act of assuming, there's neither evidence that all this is true nor need for it to be so. Many people and places in the Bible have multiple names, and Hebrew scribes often delighted in creating words and phrases via word and letter games (such as metathesis or garbling phonetics, etcetera).
🔼Etymology of the name Zererath
The name Zererath surely comes from a feminine noun derived from any of the three verbs צרר (sarar):
None of the sources we routinely consult deign to propose a translation of the name Zererath, but to a Hebrew audience it would probably have sounded like Bound. The word צררת occurs with that precise meaning in Exodus 12:34.
