The word hand, ‘יד’ is numerically 14. As we explained previously, the three hands יד יד יד of God (3×14) equal 42.
The three ייי from יד יד יד found in the YHVH יהוה of the three verses that the priests bless the children of Israel.
The three ד ד ד found in אדני אדני אדני.
The prophet Jeremiah repeats three times “Palace of YHVH” in sequence. Jeremiah 7:4 “הֵיכַל יְהוָה הֵיכַל יְהוָה, הֵיכַל יְהוָה”
The word “הֵיכַל”, ‘Palace’ numerically 65, same as ADNY אדני and ‘The vessel’, ‘הכלי’.
The meditation of the hand washing before the meal connects the three YHVH יהוה and three ADNY allowing us to have complete connection to the three columns and the Tree of Life.
Each of the three columns comes from the three sides of the Holy Creatures of the Holy Chariot, Lion (Chessed, Right), Ox (Gevurah, Left), Eagle (Tiferet, Central). They also represent the three YHVH. The three wings of the Holy Creatures is the aspect of the three D דדד that is three times אדני ADNY. All should come from the ‘force’ (כח = 28) of man (אדם Adam= 45) that is the name of Zeir Anpin and the 28 letter of the spelled name
The Shechinah with the name of 28 letters can come to the hands with the 28 segments of the fingers (14+14) only when the hands are spiritually pure.
The sages told us that the maidservant of the negative side reside on impure hands and disqualify the person from making blessings.
The water that purifies our hands is the aspect of Torah. If people don’t have the Torah and follow it, then they are like insects, aspect of the negative side and maidservant. They stay impure even after they go under the water because they don’t have the Torah to purify them.
When they make a blessing without the understanding of what is blessing and what is impurity, they are considered and robbers from the Holy One Blessed be He.
The purity of our hands and consciousness should be on the highest level in order to be able to draw true blessings into our lives from the names of YHVH that we can draw with proper blessings.
