🔼The name Hamutal in the Bible
There is only one Hamutal in the Bible, and she is the mother of kings Jehoahaz and Zedekiah of Judah (2 Kings 23:31, 24:18, Jeremiah 52:1). She is a daughter of Jeremiah of Libnah (not the famous prophet) and the wife of king Josiah (2 Kings 23:30).
Our name is spelled חמוטל (Hamutal) only in 2 Kings 23:31. In 2 Kings 24:18 and Jeremiah 52:1 it's spelled חמיטל (Hamital).
🔼Etymology of the name Hamutal
The name Hamutal consists of two elements, the latter one being the noun טל (tal), meaning dew:
The first part of the name Hamutal may be the word חם (ham), meaning either hot or father-in-law:
The first part of the name Hamutal may be the adjective חם (ham) meaning hot. But that would give this name a meaning of Hot Dew, and that's most likely incorrect. More likely is a kinship with the identical word חם (ham) meaning father-in-law.
The whole name thus means My Father-In-Law Is The Dew. Whatever poetic or other image the Hebrews had with this name is unclear, but that there must have been something is strongly argued by the existence of the similar name Abital, meaning My Father Is The Dew.
For a meaning of the name Hamutal, NOBSE Study Bible Name List reads a timid (and ultimately incorrect) Kinsman Of Dew. Jones' Dictionary of Old Testament Proper Names reads an evenly deviated Akin To The Dew. BDB Theological Dictionary states "meaning dubious; perhaps, if Kethib is right, My Husband's Father Is The Dew", and the Kethib is a collection of difficult or improbable spellings in the Hebrew Scriptures. The companion called Qere offers possible substitutes.
