Why Jews sway and nod while at prayer

People may see it all the time, Jews nodding while at prayer. Buddhist take their shoes off before entering their house of worship, the Buddhist sit on the floor for most of the worship service. Jews of which I am, sit in a pew, stand, nod, bend at the knee, and stand on their toes. Nodding could come from Psalm 35:10 which reads, My whole being will exclaim, “Who is like you O Lord? and or Proverbs  20:27 that the soul of man is God’s candle. Swaying back and forth while praying represents a candle’s flame that flickers back and forth while burning. I can go on if you like.

The idea that body movement can express devotion to God appears in the Book of Psalms: “All my limbs shall say ‘Who is like You, O Lord?’” (35:10) In Midrash Tehillim, an 11th century exegetical text, the rabbis interpret “all my limbs” quite literally:

With my head, I bend my head and bow down in prayer…And I also wear phylacteries [tefillin] on my head. With my neck, I fulfill the precept of wrapping oneself in fringes [tzitzit]. With my mouth, I praise You, as it says: “My mouth shall speak the praise of the Lord” (Psalms 145:21)…With my face, I prostrate myself, as it says: “He fell down on his face to the earth” (Genesis 48:12)… With my nose, when I smell spices with it [during the havdalah blessing said] at the outgoing of Shabbat. With my ears, I listen to the singing of the Torah.

In this text, the body is presented as a tool for praising God, mostly in terms of the way ritual objects are used on the body, but also in terms of the body’s own movements. Today, the physical actions listed in this midrash, as well as a number of other body movements, have become an established part of Jewish prayer.
