Look for the main idea or message. Keeping the main idea in mind helps to tie all the verses together. Divide the whole . Long books can be divided into smaller parts. Genesis is a prime example.
Small bits are easier to remember.
Write it down . Use rote memorization . This simply means reading several times a verse or a chapter. Reading at least ten times is best. Study a verse, chapter or story in depth, not just a superficial reading, and then review it the next day.
