Likutei Moharan 63:4/ליקוטי מוהר"ן ס״ג:ד׳

14. And the bread-of-the- panim (showbread) is the aspect of brit, as it is written (Leviticus 24:8), “On the Sabbath day he shall arrange them before God… an eternal covenant.” And of [the Holy Table] it is said (Exodus 25:25), “Make for it a frame one handbreadth wide.”

2This is why the aspect that receives the aforementioned six TeFaChim is called miTPaChat, as it is written (Ruth 3:15), “Bring the mitpachat (shawl).” For this was her request, as it is written (ibid.:9), “Spread your KaNaF (garment) over your handmaid”—she asked for the aforementioned KNaFayim (wings), which are the aspect of the six handbreadths, as explained above. Therefore, “He said to her, ‘Bring the mitpachat’ … and he measured six [measures of] barley.” These are the aspect of the six tefachim, the six wings mentioned above.
