ISB ~ Revelation 4 v5 - 6

Streaks of lightning and booming thunder (4:5) feature in revelations of Yahweh’s glory to Israel (Ex 19:16) and Ezekiel (Ezek 1:4, 13). The glassy sea recalls the clear sapphire pavement (Ex 24:10) and crystal flooring (Ezek 1:22) spread beneath the Lord on both occasions.
