The Rainbow Study Bible link is below but it appears 'additional' advertised software must also be downloaded. It is a choice.
The Rainbow Study Bible is a Bible in which the verses are highlighted by the publishers, with different colors for different subjects.
According to my Concordance, the word rainbow can be found in:Ezk 1:28Rv 4:3Rv 10:1Additional Answer:Many times it depends on the translation. In my NKJV Study Bible, the word 'rainbow' is used in Genesis 9:13.
A good site that offers free Bible study lessions is Bible.org. It is a great site and has everything you will need for your daily needs.
There are several online communities where you can get together with others and study the bible or follow a plan and study by yourself. These courses can be accessed whenever you feel, so how many times and when you study is up to you. Here is one of the many free online bible schools I found: http://www.amazingfacts.org/free-stuff/bible-studies/free-online-bible-school.aspx
One of the best home Bible study software options is Logos Bible Software which can be found at www.logos.com/. It offers you all of the study tools you need. Other options include Parsons Bible Study Software (www.quickverse.com), Bible Explorer (which is free at www.bible-explorer.com), PC Bible Study (www.biblesoft.com) and Bible Works (www.bibleworks.com/).
You can read the Bible online free or download a copy from the attached link "Read the Bible" What's great is that you can listen to it at the same time, which is wonderful because of the hard words and names to read. You can also request a free Bible study from the link: "Request free Bible Study". They will provide you with a free Bible.
I don't believe there's a "rainbow" bible
Genesis 6-- Is the story of Noah and the Ark. At the end of the story God promises that He will never flood the earth again with a gift, called the rainbow.
I could be mistaken, but I believe Bible study is free to anyone interested. Off the top of my head I would recommend speaking to a clergy member for starters and then maybe contacting local study groups.
There are many sites to choose from, one good website is "the online bible college" which offer free study plans and issue a certificate of completion upon completion.
A local church or chapel would be the best place to ask about where to find good quality free bible study lessons, either by asking the minister or the congregation. Commercially produced bible study books are inexpensive and also worth considering.
There is no description of rainbow in the Bible. It's only referred to, as "the bow".
