Q. Why do Orthodox Jews nod when they pray at the wailing wall or reading the scripture?
A. Some say this ancient tradition comes from Psalm 35:10 which reads, My whole being will exclaim, “Who is like you O Lord?” Others point to an interpretation of Proverbs 20:27 that the soul of man is God’s candle. They say swaying back and forth while praying represents a candle’s flame that flickers back and forth while burning.
