Numbers 21:6
6 fThen the Lord sent fiery serpents among the people, and gthey bit the people, so that many people of Israel died.
Isaiah 30:6
6 An woracle on xthe beasts of ythe Negeb.
Through a land of trouble and anguish,
from where come the lioness and the lion,
the adder and the zflying fiery serpent,
they carry their riches on the backs of donkeys,
and their treasures on the humps of camels,
to a people that cannot profit them.
