• This site has truly served me well. I key in a smattering of words, and walla -- it shows me the verse in the Bible. 
• I click on that verse and almost every great English translation of that verse shows up. This a quick solution if you can't understand the English of a verse from the version that you are reading!
• There are many more valuable aids in Biblos.com meant for Bible study, such as its atlas and encyclopedias. But what makes this website a winner is its powerful search mechanism and its amazing speed! It is an obvious choice to consider if you need an all-in-one Bible study tool.
