Shannon ("wise river") is an Irish name, Anglicised from Sionainn. Alternative spellings include Shannen, Shanon, Shannan, Seanan, and Siannon. The variant Shanna is an Anglicisation of Sionna ("possessor of wisdom").
In the Book of Genesis, Jehovah-jireh or Yahweh Yireh (Jehovah/Yahweh will provide) was a place in the land of Moriah. It was the location of the binding of Isaac, where God told Abraham to offer his son Isaac as a burnt offering. Abraham named the place after God provided a ram to sacrifice in place of Isaac.
