'El is another name that is translated as "God" and can be used in conjunction with other words to designate various aspects of God's character. Another word much like Shaddai, and from which many believe it derived, is shad meaning "breast" in Hebrew (some other scholars believe that the name is derived from an Akkadian word Šadu, meaning "mountain," suggesting strength and power)....' — @blueletterbible
The holy letter "Shin". It's ancient Hebrew meaning is "press, eat, consume". It is in the name El Shaddai (God Almighty), and also in the name Yeshua (Jesus). It is symbolic of the chambers of the heart.
Psalm If you say, "The Lord is my refuge," and you make the Most High your dwelling, no harm will overtake you, no disaster will come near your tent. For he will command his angels concerning you to guard you in all your ways.
