🔼The name Berothai in the Bible
The name Berothai occurs only once in the Bible. Betah and Berothai are two cities of Hadadezer, son of Rehob, king of Zobah of Moab, from which king David looted huge amounts of bronze (2 Samuel 8:8). The Chronicler calls these cities Tibhath and Cun and adds that Solomon used this bronze to make the temple's pillars, great sea and utensils (1 Chronicles 18:8). For a discussion on why these accounts may differ, see our article on the name Harodite.
🔼Etymology of the name Berothai
The name Berothai probably comes from a plural form of the noun באר (be'er), meaning well:
The letter י yod upon which our name ends can have all kinds of functions. It may turn the beroth-part into an adjective (wells-like) or a possessive (my wells). Or it may be a remnant of יה, the shorter form of יהוה, or YHWH, the name of the Lord.
For a meaning of the name Berothai, NOBSE Study Bible Name List appears to ignore the final yod and simply reads Wells. Alfred Jones (Dictionary of Old Testament Proper Names) sees in the final yod a remnant of YHWH and proposes Wells Of The Lord. BDB Theological Dictionary does not interpret Berothai but does list it under the noun באר (be'er), meaning well.
