The first three days of creation correspond to the second three days. What was created in the first three days is given its completion and position relative to the development of life on earth in the second three days, as follows:
Day 1 Light – Day 4 Light Bearers
Day 2 Water and Air Space – Day 5 A World of Life
Day 3 Dry Land with its Vegetation – Day 6 Living Inhabitants
With the seventh day, a new world started; the world of the education of Man to God. This seventh day is another first day but on higher, spiritual level. Light is again created, but this time it is the light of recognition of God. Who was given the mission to promote this recognition? This is the mission of Israel. Israel is God’s eight work of creation. The seventh day at first had no בן זוג until God told it ישראל יהיה בן זוגך.
