Emerald,

In chapter 3 of the book the authors explain on page 7: “The wording “new moon” or “new moons” is used 20 times in our KJV Old Testament. The term that is translated as “new moon” is always the same Hebrew word: “chodesh.” Likewise, without exception, the plural (“new moons”) is always the plural form of “chodesh” (“chodeshim”)…Notably, Strong’s illustrates here that the word “chodesh” does not always include the lunar aspect. It can simply mean month, monthly, or the 1st day of the month.”

If you require a more detailed explanation, I suggest you contact the authors directly. Their website is: https://www.returningtothegarden.com
