"In the beginning was the Word".....not the context.
Contexts - even correct ones - are impossible to construct (or concoct) without the words they are based upon.
Any reputable theologian deserving that title cannot legitimately interpret (either literally or figuratively) a certain word or group of words in Biblical Text in many ways and senses - which The Author intended to be interpreted ONLY in one specific way or sense.
According to Jesus in John 11:9, the rhetorical answer to the question of "Are there not 12 hours in the day" is, of course: "12." [The Greek-Text word for "day" here is: (e)meras, pronounced AIM-mer-ass, and is conceptually identical with the Hebrew-into-English capitalized word for sunlight "day" contrasted to night (i.e."Day" in Genesis 1:5)].
Substantiating that, we have the Matthew 20:1-17 Bible story of potential employees being hired at the 11th hour (a time span within the sunlit part of the "day") of the "day" mentioned in that verse [the Greek-Text verse-6 word being: (e)meran and pronounced AIM-mer-ann] which workers - after being hired and having worked only one "hour" - were complained against by other workers in that those other workers had borne the heat of the "day" [the Greek-Text verse-12 word being: (e)meras and pronounced AIM-mer-ass] but paid only as much as employees hired at "the eleventh hour."
In Hebrews 4:4, we have the statement that God "rested on the seventh "day." [The Greek-Text word for "day" here is: (e)mera and pronounced AIM-meh-rah....which (e)mera would be the equivalent of the 24-hour-time-span Hebrew word yom for TIME-span "day" (not necessarily having anything here to do with light or lack of it) in Genesis 1:5,8,13,19,23, etc.....and notice how that is slightly but vitally different than the specific Greek word for daylight-hours "day" of Matthew 20:12 and John 11:9 corresponding with the capitalized word "Day" of Genesis 1:5.
Our non-Hebrew non-Greek English language has a sordid deficiency pertaining to the words "Day" and "day" in most English-language renditions of Genesis chapter 1 of The HOLY BIBLE....in that (except for the capitalization of the word 'Day' in one instance but not in the other) it is impossible to differentiate the English-pronounced word "Day" (meaning one thing) from the English-pronounced word "day" (meaning something entirely different). Thus, there is a semantical problem of the English language between:
As The Absolute Gold Monetary Standard is "the shekel of the sanctuary" (mentioned within the Mosaic Pentateuch of Exodus chapters 30 & 38, Leviticus chapters 5 & 27, Numbers chapters 3 & 7) and The Standard Hebrew Alphabet was etched in stone by "the finger of God" Himself (in spite of the Phoenicians, Chinese, Arabs, others conniving their weird concoctions of strange lettering), so the word YOM is the Standard of Time Measurement, which YOM is subdivided into correctly-timed hours, minutes, and seconds...plus multiplied into weeks, months, and years (in accord with Christ's precise Celestial-Movement Signs-and-Seasons Timeclock)..... [not the somewhat-screwy catholic Gregorian Calendar].
Further info might be obtained from some by-BLOOD nephew or niece....OR from a by-MARRIAGE nephew-in-law, niece-in-law, uncle-in-law, aunt-in-law, grandfather-in-law, grandmother-in-law (but not necessarily from any mother-in-law, father-in-law, son-in-law, nor daughter-in-law).....nor from a by-DIVORCE
step-nephew-in-law, step-niece-in-law, etc.
This helps us solve a dilemma pertaining to the words "Day" and "day" in Genesis 1:5.
In the Hebrew Text, close inspection of the Hebrew lettering of both "Day" and "day" in Genesis 1:5 plainly shows that (except for a slight extra Masoretic marking on one of those words) the precise Hebrew lettering of BOTH Hebrew words is exactly identical. Which therefore nondeniably indicates that Day = day = yom = light. That being the case, where is there any place for night, darkness, and evening mentioned in Genesis chapter one?
In other words, if the totality of the 24-hour yom is equivalent to "day" and "light" when is there any time left for night, darkness, and evening?
Obviously, the inspired writer of Genesis - having the mind of Christ and His apostle John - was thinking positively, and although negative was mentioned as also existent, the positive was what was stated with multiple-meaning word "Day"/"day" (having "positive" referring to "light" and "negative" referring to "darkness, night, and/or evening)."
Our modern knowledgeable view of what Isaiah 40:22 calls "the circle of the Earth" helps us understand that phenomenon, enhanced by NASA photos from launched spacecraft of our rather-spherical ball-shaped planet proving that sunlight from the Sun lights up half of our rotating Earth continually. Mostly likely not only Job but Isaiah saw the full moon appear at times each month as a circle in the night sky, and sensed that the sunlight ruled half of each consecutive 24-hour period while the moonlight and starlight ruled the nights of those consecutive periods. We know that sunlight is always lighting up one half of this planet as the planet turns on its axis. In that sense, there is always "day" present on half of the planet's surface, and from point-to-point at any given same spot during a 24-hour yom period a 24-hour "day" will have elapsed over changing areas of the entire surface of Earth.
