Hissalel
Hissalel ben Amminadab was an Ammonite king of the late seventh century BCE, reigning approximately 620 BCE. He is mentioned on an inscription on a bronze situla found at Tel Siran in Jordan. The inscription reads: mndb mlk bn'mn / bn hsl'l mlk bn'mn / bn'mndb mlk bn'mn " Amminadab (II) son of Hassal'il son of Amminadab (I)."
His name, which invokes the name of the god El (as do the names of his fellow Ammonite kings Pado'el and Barakel suggests that El was worshipped in Ammon alongside Milcom and other deities.
