Thank you for asking a question on www.thisisyourbible.com
According to Rotherham, the first one, to my knowledge to use the term "Yahweh" in his well-respected translation, "The Emphasized Bible", the word occurs 5,790 times in the Old Testament.
If you want to come to grips with what the Bible really teaches, why not take the free Bible study course on www.thisisyourbible.com? You may take this course either online or by regular mail.
This course will give you a background in the major themes of the Bible from Genesis to Revelation. As with everything we offer, there is no cost to you other than your time and effort. You will also have a personal tutor to whom you may pose questions either from the course itself or those questions which come to you as you read the Bible.
I hope you have found this helpful.
May God bless you,
