If you want to add Learn Scripture to a phones homepage, go to the website on your browser, go to the share button (where you can share the website address, or add a bookmark or favorite), and “add to homepage” should be an option among adding to favorites/bookmarks/reading lists. Hope this helps!
Good to see and may the Lord bless your study and memorisation. In my church we have a weekly Bible Study that is slowly going through Hebrews. We are just about to start Hebrews 3, but that has taken several weeks, to get that far.
I’m finding it’s good to take it slowly, and to consider the book as a whole. The author circles round the same themes several times, so you find verses in one chapter that shadow or foreshadow a similar section in another chapter.
