For, behold, the darkness shall cover the earth, and gross darkness the people: but the LORD shall arise upon thee, and his glory shall be seen upon thee.
Darkness shall cover the earth - the rest of the earth: in contrast with 'thy light, and the glory of the Lord risen upon thee' (Isaiah 60:1). The earth will be afterward enlightened through Israel (Isaiah 9:2).
But ... his glory shall be seen upon thee - conspicuously: so the Hebrew, yeeraa'eh (H7200).
