I use Bible Gateway for an easy to use index, and you can get ANY version you want. There are preferences that you can set for yourself. It has a very easy to use keyword search feature.

The other that I like is this.....
It allows for parallel comparisons on one page of a verse and among the tabs it offers is the Greek or Hebrew and then links to a Strong’s Exhaustive Concordance.
That’s where I’ve been getting the information on the Greek meanings of the words. It’s not hard to find your way around. Even someone as computer illiterate as I can find my way around those websites. They’re both very user friendly.
I use those as well. They are great resource tools for anyone who truly wants to find the truth of scripture. The Greek and Hebrew interlinear are especially illuminating. The subtle word changes or insertions in some versions of the Bible that many people use are particularly disturbing. I have discovered that fully trusting anyone after the Apostle John wrote Revelation is risky at best. The admonition of Paul to “search the scriptures daily” is wise counsel.
