The double bars || in the Ancient Roots Translinear Bible (ARTB) mean that the word is stated and stated again in Hebrew. This peculiarity of Hebrew will be seen over 800 times in the Old Testament. Other Bible translations don't show two words. They either drop the second word or use another adjective to describe the main word. In Genesis 2:16,17 God says
"||Eat|| of any tree of the garden, 17but never eat of the tree of the knowledge of good and evil. The day you eat from it, you will ||die||!"
