King James Bible
"And the evening and the morning were the fourth day."
This formula marks the completion of a full day in the Hebrew reckoning, where days begin at sunset rather than sunrise. The pattern emphasizes the orderly rhythm of creation, with each day having clear boundaries and divine purpose. The fourth day concludes God's creation of the celestial bodies—sun, moon, and stars—which were made to govern time and seasons. This numbering shows creation's systematic progression toward completion, with each day building upon the previous work.
