I am amazed at the number of free Bible study resources that are available online. Of course, the pre-eminent Bible study software is Logos, but it is expensive. If you’re a pastor or Bible teacher, it may be worth the expense. However, for everyone else, these websites can help you with your studies. At least, these are the tools I use regularly.
- BibleGateway.com
Although I use this site every day, I only use it in a limited way, namely, to look up passages in the NKJV and to compare it with other lesser-known translations. I know the site has more features than that. For example, my wife’s friends were recently talking about using the audio Bible feature that lets them listen to Scripture being read as they do other things. https://www.biblegateway.com/
- BibleHub.com
I use BibleHub for two main reasons. First, I use it as an interlinear with a basic lexicon where I can look up certain words and where else they appear in the Bible:

Second, it also lets me compare several translations at a glance:

- Precept Austin
I have quite a few commentaries, but I can always use more. Precept Austin has a ton of free commentaries you can look up by book, chapter, or verse:

- PlymouthBrethren.org
This site has articles by Plymouth Brethren writers (including Zane Hodges) who were Dispensational and Premillennial. It is a very useful collection, covering a wide range of topics. More than you can read in one lifetime.
