🔼The name Hathath in the Bible
The name Hathath occurs only one time in the Bible, although it's not wholly clear whether Hathath is supposed to be a name. If it is, then it belongs to a son of Othniel of Judah (1 Chronicles 4:13). The problem is that the Hebrew speaks of sons, not son, and this "name" is identical to a word meaning terror.
If the Chronicler would have wanted to submit that the many unnamed sons of Othniel were a terror, he or she would have written the exact same text. It means exactly that.
But from ancient times translators have endowed Othniel with one son named Hathath, and thus all modern translations do the same thing.
