Bible Gateway offers a variety of study resources on its website, BibleGateway.com, including study Bibles, commentaries, dictionaries, encyclopedias and more. Study resources are displayed alongside the Scripture they discuss. In other words, they are right next to the book, chapter and verse you are reading.
To access study resources for a particular Bible passage, look up the Bible passage you have in mind (for example John 1:1-5) and then look to the right of the Bible text for the Resources tab.
Clicking on the Resources tab will open a column that shows all the resources related to the Bible passage you're reading on the left. Each resource lists a number of entries to show how many references to the Bible passage that resource contains. Resources with a blue 'PLUS' badge are accessible to Bible Gateway Plus members. Resources without the 'PLUS' badge are free for anyone to use.
To read from a study resource, simply click on it, choose what you want to read from the list, and the text will be displayed without disrupting the Bible passage you're reading to the left:
To hide the reference window, click on the arrow in the upper right corner.
This button will also open the Resources, Hebrew/Greek and Your Content tabs if they are hidden.
