BibleTools info was started in 2014 by an undergraduate student who wanted a simple way to find relevant resources to specific Bible verses. Initially, he did not expect the website to prove useful to many people besides a few friends, but the word spread and people from all over the globe started regularly using it. There's a wealth of information out there to provide explanations for difficult to understand Bible verses, but finding these in a timely manner can take painstaking effort. And though BibleTools will never be an end-all due to copyright restrictions, we hope it will continue to prove useful to many people as we continue to add additional resources.
