“Shamayim is a Hebrew word that refers to a beautiful sky full of fire. The word is a construct of the Hebrew words esh (fire) and mayim (water), forming the heavens.”
Shamayim (Hebrew: שָׁמַיִם šāmayīm, "heavens") is the dwelling place of God and other heavenly beings according to the Bible. It is one of three components of the biblical cosmology. There are two other ones. Eretz (Earth), home of the living, and sheol (the common grave), the realm of the dead
“Exodus 24, Ezekiel 1, Isaiah 6, 2 Chronicles 18 and 1 Kings 22 describe God seated on a throne, with angels surrounding him. Exodus 24:10 describes a pavement made of sapphire or lapis lazuli.
Ezekiel 1 describes a throne room made of angels and God's throne being seated on a flying angel. Isaiah 6 describes an altar standing before God's throne. 2 Chronicles 18 and 1 Kings 22 describe angels to the right and the left of God, like prosecutors and defendants to the right and left of a judge in a bet din. Judaism interprets the visions symbolically, rather than as literal descriptions of heaven.”
