וְגָלְלוּ אֶת-הָאֶבֶן מֵעַל פִּי הַבְּאֵר
and they rolled the stone from the well's mouth ... Bereshit 29:3
The Hebrew word used in this phrase for stone is ha-avan (האבן meaning "the stone"). Ha-avan is derived from the same root as the word me-avanei (מאבני meaning "my petrified/fossilized stone"), the stone upon which Jacob rested his head during his angelic encounter in Bereshit 28:11 -
וַיִּקַּח מֵאַבְנֵי הַמָּקוֹם
and he took one of the stones of the place ...
Importantly, both words, namely ha-avan and me-avanei, are derived from the shoresh (three letter Hebrew root) אבן which means "to create using a special tool." The shoresh itself is derived from the sha'ar (two letter Hebrew root) בן. The sha'ar בן pertains to "building", "understanding" and to the idea of something being "composed of." These roots are most directly associated with functions of the feminine sefirah Binah (בינה) and to the creation of somethings "becoming composed of" matter and becoming infused with the basic energy of mindful intelligence. Taken together, we can understand that the sha'ar, shoresh and words along the intra-root continuum of בן - האבן - אבן - מאבני - pertain to an ever increasing particularization of 'something' into matter. In other words, when we are using roots and words derived from the sha'ar בן we are specifically using roots and words linked to the origin and development of an esoteric quantum mechanical particle within the wave-particle complementary nature of elementary light, energy and matter.
Another word in Hebrew for stone is gal'ayin (גַּלְעִין), derived from the shoresh גלע which means "reveal" and "uncover." The shoresh itself is derived from the sha'ar גל. The sha'ar גל pertains to a "wave movement", a "wave style" and "rejoicing." Eureka! Rejoice! we can understand then that the sha'ar from which the stone gal'ayin derives pertains to 'almost something' which is not materialized into particle matter. In other words, gal'ayin refers to the 'almost something' quantum complementary wave-nature of elementary light, energy and matter.
The sha'ar בן solidifies matter and pertains to particularity. On the other hand, the sha'ar גל reveals the essential nonmateriality of matter and pertains to the universality of which particularity partakes on its way into manifest existence. Taken together both she'arim occupy a continuum of unified consciousness able to exquisitely act within many frames of experience simultaneously, even particularity and universality.
The sha'ar גל is used in Bereshit 9:21 - וַיִּתְגַּל בְּתוֹךְ אָהֳלֹה - and it was uncovered in her tent.
