Hazelelponi, also spelled Hazzelelponi (Hebrew: הַצְלֶלְפּוֹנִי, shade coming upon me) is mentioned in 1 Chronicles 4:3. She was the daughter of Etam, sister of Jezreel, Ishma and Idbash, of the tribe of Judah.
A similarly named woman, Z'llpunith or Zlelponith, is referred to in rabbinical sources - Midrash Numbers Rabbah Naso 10 and Bava Batra 91a[1] - as being the mother of Samson.
