Holy bible of eternal life and healing without medication. Job 38:4-7 according to the Gregorian Calendar (1520 B.C.)
4“Where were you when I laid the earth’s foundation?
Tell me, if you understand.
5Who marked off its dimensions? Surely you know!
Who stretched a measuring line across it?
6On what were its footings set,
or who laid its cornerstone—
7while the morning stars sang together
and all the angels shouted for joy?
Angels are Sons of God.
