Common questions

Is this Bible commentary free?

Yes. Background and commentary for all 66 books are free to read here, with no account and no email. In the Protos app the same commentary sits verse by verse beside the text.

What does a Bible commentary tell you?

Who wrote the book, when, to whom, and what they were dealing with, then what the text is doing as it goes. It is the context a passage assumes you already have and most of us do not.

Which commentary is this?

Tyndale Open Study Notes, licensed CC BY-SA 4.0, for 65 of the 66 books. Judges is the exception and uses Jamieson, Fausset and Brown (1871), which is public domain. Protos compiles the figures on each page and the people and places it lists, keeping same-name figures apart.

Read it in context

Read the commentary beside the text, not after it.

Protos carries this commentary verse by verse alongside the passage, with the dictionary and the original languages on the same screen.

Portrait of Jason Layantara
“Been using Protos for months now. Protos is an amazing Bible study app for anyone who wants to grow deeper in God's Word. I love how it helps me understand Scripture beyond simply reading the verses, providing helpful historical context, commentary, and insights into the original Hebrew and Greek. The resources make it easier to engage with the Bible and grow in understanding.”

"People often think they have a discipline problem because they struggle to read the Bible for more than a few minutes, while they can watch movies for hours. It may not be an attention-span problem so much as an immersion problem: when you understand the story, the people, the world, and what is happening, two hours can disappear. But when you do not understand what you are reading, even ten minutes can feel like work. So you skim past the words and jump straight to what the passage means for you before you have listened to what God is saying through the text, the story, and the voice of the writer. It happens so often that theology has a name for it: eisegesis."
Fabio Jonathan ArifinFabio JonathanFounder of Protos · Portland Bible College graduate

Protos helps you close that gap so you can stop skimming and start getting immersed in the world of the Bible.

The streak feature actually got people in my congregation excited to read, especially the youth. We've started comparing notes after service.
