Day in Genesis

Recently, Kevin DeYoung said that the most important thing for Christians in debate is to actually open up the Bible and work through the text. Don't settle for vague impressions or general ideas. What does the Bible actually say? I put this idea to work by looking at the use of the word "day" in the Pentateuch (Genesis-Deuteronomy). 

The impression is often given by Old Earth Creationists that the Hebrew word for "day" (yom) is a flexible word that has a broad range of meaning. This idea has been used over and over again by men to create enough elasticity in Genesis 1 so that one can put billions of years in the creation account. But is it true that this word is as flexible as OEC would like it to be? I decided to open up the text and see for myself. . I went through and looked at all the uses of the word day in Genesis, Exodus, Leviticus, Numbers and Deuteronomy to determine if what the OEC men claim to be true is actually true. This was tedious and it makes for tedious reading. But the point I want to make is that when one reads the word "day" in the Bible it almost always means a typical 24 hour day. 

This study is based on the ESV translation. I do not have the ability to search in Hebrew, but I can read Hebrew and I have several Hebrew word study helps as well as a Hebrew Old Testament. I checked the words to see if they were really “yom.” They almost always were. Occasionally you will find the word “day” supplied where it is not in the Hebrew (i.e. Leviticus 23:5, 27). It is clear in those places that “day” is implied though not specifically written. Also sometimes instead of the word being “yom” it is the word “yomam,” which means “daily/daytime” (i.e. Numbers 14:14). Often the ESV translates “yomam” as “day.” The words are clearly connected. I have not purposely included the plural use of “yom” though if it showed up in my search I kept it.

I have divided these up into three categories: All the uses of day with a number, all the uses of day which in context mean a typical 24 hour day, and any uses of day which could mean a long period of time. 

All uses of Day with a Number (1^st, 2^nd, 3^rd, etc.)

Places Where Day Can Mean a Long Period of Time
There are no texts in Genesis 3-50 where day can mean a long period of time.

The research shows the following:
Every time in Genesis 3-50 the word day is used with a number it means a 24 hour day.
When it is not used with the number it still points to a specific day in the past, present, or future. 
Nowhere in Genesis 3-50 is the word day ever used to mean a long period of time. 

In the future I will look more closely at the word day in Genesis 1-2.
