The reason I said that Yom is Light is because, not only is it true, (for Elohim calls the Yom, Light, Gen 1:5), but because yom therefore may be any increment of time, not just what we call in modern reckoning a "day". We find in the scripture a yom for a day in many, many places, but we also find a year for a day when the spies brought back an evil report on the land, (forty years for the forty days they went to spy out the land). Then we also find a day for a year in the Prophet Ezekiel, for the days he is commanded to lay on his right and left sides for the transgressions of Yhudah and Yisrael, each day for a year. We also find that one day is as a thousand years with the Master, and a thousand years are as one day, (2Pet 3:8), and this is likely based on Psalm 90, (a prayer of Mosheh), where we find that a thousand years in the eyes of the Most High are as yesterday when it is passed, and as a watch in the night, which is a mere four hours.
If therefore a yom may be a day, and a yom may be a year, and a yom may be as a thousand years, and a thousand years as one yom, and as a watch of the night which is a mere four hours, then no doubt a yom may also be an hour: for it is an hour of light, for yom is light, (Gen 1:5, according to the name which Elohim Himself names it when He calls the Light, Yom).
We therefore have the sacred calendar day laid out for us in the opening creation account: seven yamim-hours in the yom-day wherein Elohim made Earth and Heavens, (He made all in a single yom-day according to the statement in Gen 2:4). And we therefore also have the twelve hour civil calendar day laid out for us in Numbers 7, wherein each prince of the twelve tribes offers the korban offering for his tribe, each prince in his own yom-hour, (Num 7:11), of the yom-day wherein the altar was anointed, (read carefully: every yom offering occurs within the single yom-day wherein the altar was anointed, Num 7:10, Num 7:84).
The question from the Master to his talmidim-disciples in John 11:9, "Are there not twelve hours of the day?", cannot rightfully be answered except from the scripture: for we are all to be taught of Elohim, and the Master himself repeats this from Isaiah the Prophet in John 6:45, (prophets, plural, Isa 54:13 and probably also intending Jer 31:34). The answer to the question that is pleasing to the Father would therefore come from His Word, not of man teachers.
So if we were to take the question as pointed also to ourselves, as well as to his talmidim, how shall we answer it? Shall we say, "Oh, yes indeed, there are twelve hours in a day because the Sanhedrin says so"??? (Unacceptable). Shall we say, "Oh, yes of course, Roman time keeping tells us there are twelve hours of day and twelve hours of night"??? This too would be unacceptable: for if indeed we are taught of Elohim by His Word then the pleasing answer must come from His Word and our understanding of it, having been taught by Him and His Word in such matters, as in all things.
The only place one may find a teaching of twelve hours in a day is Numbers 7, but what we read in English translations are for the most part misleading in this respect, and therefore a study of the original language is necessary. There is no need for me to try to explain all of the reasons why, and bog down this thread: anyone who is interested can research these things for themselves, and may Elohim bless their understanding in their prayerful studies in His Word.
