(Hebrew Lappidoth', לִפַּידוֹת , Torches; Sept. Λαφιδώθ ), the husband of Deborah the prophetess ( Judges 4:4). He may have resided with her at the time of her public services as female judge ( Judges 4:5), or more probably he was deceased. and she is named as his widow. B.C. ante 1409. From the fact that the name is in the form of a fem. plur., some have taken it to mean her place of residence ( אֵשֶׁת , Woman Of, being understood before it), but without probability (Bertheau, ad loc.). By others the term Lappidoth has been understood to denote merely her character (q.d. "woman of splendors," i.e., noble, brilliant), or even her occupation merely (q.d. Lamp- Trimmer); but all these are equally nugatory suppositions. (See Deborah).
