Jehucal or Jucal (Hebrew יְהוּכַל Yəhūḵal "Yah is able" )] is mentioned in chapters 37 and 38 of the Book of Jeremiah:
King Zedekiah sent Jehucal son of Shelemiah and the priest Zephaniah son of Maaseiah to the prophet Jeremiah, saying `Please pray for us to the Lord our God`
Excavations conducted by the Ir David Foundation in the City of David have uncovered a bulla (clay seal) bearing his name.
