Yahweh first emerges as a personal, covenantal deity in the story of Abraham.

Yahweh in Genesis 1 to 11

Setup of Earth for Humans

Genesis 1 attributes the creation of the Earth and its preparation for humans to Elohim, not Yahweh. In the KJV, Elohim is rendered “God” and the name YHWH is rendered “the LORD”.

Creation of the First Humans

In Genesis 2, the term Yahweh Elohim (“the LORD God”) appears, but this may represent a later editorial addition to align earlier traditions with Yahweh worship. See Yahweh woven through the Hebrew Scriptures and YHWH might be a later insertion replacing Elohim.

The account of Adam and Eve has no covenant of the kind later made with Abraham and at Sinai. Genesis 4:26 already says that in the days of Enos “began men to call upon the name of the LORD.”

The Great Flood

The flood narrative in Genesis 6–9 uses both names. Elohim appears in some passages, and the LORD (YHWH) in others, including the decision to destroy humanity (Genesis 6:7) and the closing of the ark:

And they that went in, went in male and female of all flesh, as God had commanded him: and the LORD shut him in.

Genesis 7:16 (KJV)

One verse of the flood story names both God and the LORD.

In the Mesopotamian flood story told in the Epic of Gilgamesh, it is Enlil who brings about the flood. Some readers take this parallel to mean that Yahweh was not the original actor in the story. See Gilgamesh: The King of Uruk, Enkidu and the Flood.

When Does Yahweh Become Central?

In the Bible’s own sequence, Yahweh’s role grows in several stages.

Abrahamic Covenant (Genesis 12–22)

Yahweh first emerges as a personal, covenantal deity in the story of Abraham. The narrative moves from the creation of all humanity to a bond with one family and, through it, one people (Israel). Circumcision (Genesis 17) and the promise of land mark that covenant.

Exodus and the Formation of a Nation

In Exodus, Yahweh frees Israel from Egypt, gives the law and the covenant at Sinai (Exodus 20), and leads the people through the wilderness as a warrior god. See Confrontation between Yahweh and the Egyptian Gods.

Yahweh as a National Deity (Iron Age)

Most scholars place Yahweh’s origin in the south, in the region of Seir, Edom, Paran and Teman. The Kenite hypothesis holds that his cult was Kenite or Midianite and reached Israel along trade routes. An Egyptian inscription at Soleb from the time of Amenhotep III (1390–1352 BCE) mentions a “land of the Shasu of Yhw”, nomads from Midian and Edom, though the link to the god’s name is uncertain.

His rise coincides with the consolidation of Israelite identity during the Iron Age (c. 1200–600 BCE). In this period, worship of Yahweh moves from honoring one god among many (henotheism) to worshipping him alone (monotheism). For the gods worshipped beside him, see Trinity: El, YHWH, Asherah and “His Asherah”.

The Prophetic Era

From the 8th century BCE onward, prophets such as Isaiah, Jeremiah and Ezekiel present Yahweh as a universal moral authority. The focus widens from Israel’s covenant to justice for all nations and hope for the end of days.

Yahweh’s Role in Human Development

The stages above line up with turning points in the history of Israel:

• Tribal organization: in the Exodus narrative, Yahweh unites nomadic tribes into one people.
• Ethical monotheism: the Ten Commandments set moral and legal codes that shaped later ideas of law and justice.
• Nation-building: under Saul, David and Solomon, Israel moves from a loose confederation of tribes to a kingdom, with Yahweh’s worship at its center.
• Exile and return: during the Babylonian Exile (6th century BCE), the emphasis shifts to endurance and hope for restoration.

Why Does Yahweh Become Central Later?

Several explanations are offered:

• Cultural change: fertility and storm gods such as Baal and Asherah served farming societies. A god of covenant, law and justice fits larger, more complex societies.
• Syncretism: Yahweh may have absorbed traits of earlier gods such as El and, some argue, Enlil.
• Progressive revelation: a theological reading holds that God revealed himself step by step as humanity matured.

Genealogy from Noah to Abraham

Before Abraham

• Creation (Genesis 1–2): Elohim and Yahweh Elohim are used, with no covenant.
• The Flood (Genesis 6–9): both Elohim and the LORD act as judge.
• Table of Nations (Genesis 10): the nations are traced from Noah’s sons Shem, Ham and Japheth. The LORD is named only in passing, in the saying about Nimrod, “the mighty hunter before the LORD” (Genesis 10:9).
• Tower of Babel (Genesis 11:1–9): the LORD confounds the language of all the earth and scatters the people.

The genealogy of Genesis 11:10–32 then narrows from Shem to Terah, Abraham’s father. The LORD is not mentioned in it.

Yahweh’s Covenant with Abraham

Yahweh first makes a covenant with Abram (later Abraham) in Genesis 12. The call comes with no account of any earlier contact:

Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father’s house, unto a land that I will shew thee:

Genesis 12:1 (KJV)

The LORD tells Abram to leave his country and family.

This raises two questions. Why is Abram chosen at this point? And did Abram already know Yahweh?

Possible answers include:

1. Abram’s background: Abram comes from Ur of the Chaldees (Genesis 11:31), a Mesopotamian city where many gods were worshipped, among them the moon god Sin. His call can be read as a break with that background.
2. A chosen line: the call sets apart a lineage distinct from other nations.
3. Editorial work: the sudden appearance may be an editorial addition that ties earlier genealogies to later Israelite theology.

Years from Shem to Abraham

Genesis 11:10–32 gives the age of each father at the birth of his son. The numbers differ between the Hebrew (Masoretic) text, the Samaritan Pentateuch and the Greek Septuagint. The Septuagint also adds a generation, Cainan, between Arphaxad and Salah.

Person	Masoretic (KJV)	Samaritan	Septuagint (Lucian)
Shem	100	100	100
Arphaxad	35	135	135
Cainan	–	–	130
Salah	30	130	130
Eber	34	134	134

Terah	70	70	70
Total to Abram's birth	390	1040	1270
Combined lifespans	2996	2876	4076

Hebrew text: 390 years from Shem becoming a father to the birth of Abram, with combined lifespans of 2996 years. Shem’s son was born two years after the Flood (Genesis 11:10), so Abram is born 292 years after the Flood.

Samaritan Pentateuch: 1040 years, with combined lifespans of 2876 years.

Septuagint (Lucian): 1270 years including Cainan, or 1140 without him, with combined lifespans of 4076 years.
