Martin Luther on Bible Study

Here is an oft quoted remark attributed to Martin Luther.

"I study my Bible like I gather apples. First, I shake the whole tree that the ripest may fall. Then I shake each limb, and when I have shaken each limb, I shake each branch and every twig. Then I look under every leaf. I search the Bible as a whole like shaking the whole tree. Then I shake every limb–study book after book. Then I shake every branch, giving attention to the chapters. Then I shake every twig, or a careful study of the paragraphs and sentences and words and their meanings."
