'Beginning' in the Bible

In the beginning God created the heavens and the earth.

And he journeyed from place to place from the Negev as far as Bethel. He returned to the place where he had pitched his tent at the beginning, between Bethel and Ai.

They sat before him, arranged by order of birth, beginning with the firstborn and ending with the youngest. The men looked at each other in astonishment.

Reuben, you are my firstborn, my might and the beginning of my strength, outstanding in dignity, outstanding in power.
