"I will uphold thee with the right hand of my righteousness”
The Ancients who understood spiritual energy have found that when one raises one's arm to the square, as when taking an oath, the arm acts as an antenna to draw spiritual energy, increasing and magnifying the power of the spoken words.
Moses raised his right arm in the parting of the Red Sea and the elements obeyed his words.
Christ with his right arm to the square as he spoke the words for Lazarus to rise from the grave.
Native Americans raise their right arm in a greeting, increasing the power of their saluation of hello.
When taking on an oath to preserve, protect, and defend the Constitution of the United States, the President will raise their right hand to the square. Those entering the militiary as well as any public office will also raise their right arm to the square. Those testifying in court raise their right hand to the square.
When a church member is newly baptized or moves into the geographic boundaries of a ward or branch, the individual's name is presented to the congregation and members are invited to raise their right hand to welcome that member. We also raise our right hand to sustain or give a vote of thanks for those in their ward callings.
There are many other examples that I could share, some of which are sacred.
I found this interesting that all through the generations on this earth we can see the importance of the arm raised to the square..which is a symbol as well as a literal means to increase and magnify the power of the spoken words.
Some scriptural references:
“The predominance of right-handedness provided a ready basis for metaphors and geographic perspective in the Ancient Near East…In social concourse, oaths and agreements were affirmed with the right hand (Gen. 14:22; Ezek 17:18; Dan 12:7), expressions of fellowship were sealed with a right-handed handshake (Ezra 10:19), and giving and receiving were done with the right hand (Ps 26:10; Gal 2:9).” (Dictionary of Biblical Imagery 727-728)
