"Variant of Jael"
The name Jahel is commonly a male name from the "Hebrew" origin.
Jahel is a spelling of the biblical name Jael, the form used in the Latin Vulgate and carried into the Douay-Rheims English translation of the book of Judges, where Jahel is the wife of Heber the Kenite. The Hebrew name behind it, ya'el, is the ordinary Hebrew word for the ibex or mountain goat. The spelling is a variant of the same name rather than a separate coinage.
Jael means "Wild goat. Wife of Heber. ".
The pronunciation of Jahel is jah-HEL.
