Is Genesis 1:13 a literal 24-hour day?
Does Genesis 1:13 support a literal 24-hour day interpretation?

Text of Genesis 1:13

“And there was evening, and there was morning—the third day.”


“Evening and Morning” Formula

Genesis 1:13 repeats the refrain already used in verses 5 and 8. Hebrew narrative typically sequences time in sunrise-to-sunrise or sunset-to-sunset cycles. Exodus 27:21, Leviticus 24:3, and Daniel 8:14 employ exactly the same phrase to mark literal day-night spans. The physical realities of darkness (evening) followed by light (morning) picture a natural rotation of the earth under a fixed light source created in verse 3, anticipating the installation of the sun on Day 4.


Ordinal + Yōm Rule

Outside Genesis 1, whenever yōm is numbered (e.g., “on the seventh day” in Exodus 16:26), it is universally a 24-hour period. Because Hebrew lacks a separate word meaning “age” or “epoch” that can accommodate the ordinal, ancient narrators would have employed alternative constructions (“in the days of…”) had long eras been intended.


Comparison with the Sabbath Commandment

Exodus 20:8–11 roots the weekly Sabbath in God’s own work pattern: “For in six days YHWH made the heavens and the earth… and He rested on the seventh day.” If Genesis 1 used figurative ages, the Fourth Commandment would set an impossible model: six vast eons followed by one literal day of rest. Moses’ audience understood the sequence as six literal workdays culminating in a literal Sabbath. The statute loses force under a long-age reading.


Immediate Literary Context

Genesis 1 is narrative prose marked by wayyiqtol verbs (“and God said,” “and God saw”). These sequential verbs, coupled with specific time markers, distinguish the passage from Hebrew poetry (e.g., Psalm 104) or apocalyptic vision (e.g., Zechariah 1). The author clearly intends chronological reportage, not metaphor.


Ancient Near-Eastern Background

Egyptian, Sumerian, and Babylonian cosmogonies employ mythic cycles and conflict motifs. Genesis counters them with a concise, workmanlike timetable structured as a work week—an apologetic strategy that collapses pagan multiplicity into the singular Lord who acts in measured, literal days.


Patristic and Rabbinic Witness

• Philo (On the Creation, §27) and Josephus (Antiquities 1.27) read the days as ordinary.

• Early Church Fathers—Basil (Hexaemeron 2.8), Lactantius (Divine Institutes 7.14), and Theophilus of Antioch (Ad Autolycum 2.11)—speak of six literal days.

• Rabbinic tradition (Midrash Rabbah, Genesis 3.7) assumes 24-hour cycles. Non-literal interpretations arise primarily after the rise of uniformitarian geology in the 19th century.


Genealogical Constraints

Genesis 5 and 11 chain father-to-son ages, leaving no elastic gaps. Luke 3:36-38 imports that chain into the New Testament genealogy of Christ. Adding the summed spans yields a human timeline consistent with a recent creation, corroborating Bishop Ussher’s 4004 BC date within a modest margin.


Scientific Corroboration

1. Earth rotation defines the day independent of the sun; photosensitive life on hydrothermal vents today illustrates the possibility of pre-Day-4 photosynthesis under God-provided light.

2. Global basalt cooling rates, helium diffusion in zircons (RATE Project), and soft tissue in Mesozoic fossils (Schweitzer 2005, 2007) fit young-earth timescales better than multi-million-year frameworks.

3. Polonium radiohalos in granites (Gentry 1986) require near-instant crystallization, consistent with rapid Day-3 continental formation.


Common Objections Answered

• “Day” sometimes means “age” (e.g., “the day of the Lord”): True, but never with ordinal + “evening and morning.”

• “Sun isn’t created until Day 4”: Day length is defined by earth’s rotation; initial light (1:3) provides the diurnal cycle.

• “Genesis 2 rewords the timeline”: Chapter 2 zooms into Day 6; wayyiqtol sequence in chapter 1 remains unaffected.


Archaeological Confirmation

Tablets from Ebla (c. 2300 BC) reference a seven-day week. Garrison excavations at Ugarit (KTU 1.24) show labor cycles mirroring a six-day work pattern with a rest day, supporting the antiquity of the literal week.


Philosophical Considerations

Clarity is a moral attribute of divine revelation (Deuteronomy 30:11-14). A God who seeks relationship communicates plainly. Genesis 1’s repeated cadence (“evening…morning…the nth day”) is pedagogical, anticipating memorization and liturgical use.


Resurrection Connection

Jesus validated the Mosaic authorship and historical accuracy of Genesis (Mark 10:6). His bodily resurrection—attested by multiple independent sources and post-mortem appearances to over five hundred witnesses (1 Corinthians 15:6)—secures His authority on creation. The risen Christ is the Logos (John 1:3), the active agent of the six-day creation, making His word on the matter final.


Conclusion

Linguistic, contextual, theological, historical, and scientific considerations converge to affirm that Genesis 1:13, within the larger Creation narrative, unequivocally supports a literal 24-hour day. Rejecting this interpretation strains the Hebrew text, disrupts biblical theology, and erodes the coherence of the gospel rooted in a recent, good creation marred by subsequent human sin and redeemed through the resurrected Christ.
