[79a top] Maharal: The three defining Jewish traits correlate to the three Avos (forefathers): Kindliness = Avraham (he always had his tent open for everyone to come through), Bashfulness = Yitzchak (all about fear, and self-sacrifice), Mercifulness = Yaakov (as discussed when telling his children to go down to Egypt).

All threes are inherently the same: Avraham-Yitzchak-Yaakov, Kindliness-Bashfulness-Mercifulness, Torah-Avodah-GemilusChassadim, Water-Fire-Wind, idol worship-adultery-killing, Right-Left-Middle, Father-Mother-Child, Mercy-Judgement-Truth, Chachma-Binah-Daas… We must look deep to the core centralities to gain more of an understanding of our world and through it connect to our ultimate universal Source.
