Afterlife

The first reference to afterlife comes from Genesis 1:1

Ge 1:1 ¶ In the beginning God created the heavens and the earth.

Examine the word שמים heavens:

Just as the י yud (h. new creation) is in the midst of the מים waters, it is in the midst of שמים heaven when the ש (h. Spirit) hovers over the מים waters.

The ש (h. Spirit) represents the word of God (the ו vav on the right side) returning with a bride (the two ז zayins on the left side). The implication is that the bride coexists with deity after the marriage.
