Kabbalah sa Isaias 41:8: Zohar, Sefer Yetzirah Gra Version, Sha'arei Orah & Sefer HaBahir

See now, Abraham sought to draw near to God, and he succeeded. So it is written, “Thou didst love righteousness and hate wickedness” (Ps. 45, 8), and it is further written, “Abraham who loves me” (Is. 41, 8), i.e. Abram is said to have “loved God” because he loved righteousness; this was Abram’s love of God, in which he excelled all his contemporaries, who were obstinate of heart and far from righteousness, as has been said.’

When the patriarch Abraham comprehended the great truism, revolved it in his mind, conceived it perfectly, made careful investigations and profound inquiries, pondered upon it and succeeded in contemplations, the Lord of the Universe appeared to him, called him his friend, made with him a covenant between the ten fingers of his hands, which is the covenant of the tongue, and the covenant between the ten toes of his feet, which is the covenant of circumcision, and said of him : "Before I formed thee in the belly I knew thee." (Jer. I, 5.)

Now, prepare your heart, be attentive, and hear the meaning of this verse. E”l-א״ל is the secret of HaShem’s-יהו"ה upper quality that is utterly merciful-Rachamim. Before Her all the camps of judgment-Din are lowered and humbled, so that none can stand up to Her. Now, because Avraham loved and inherited HaShem’s-יהו"ה quality of E”l-א״ל, he also merited to inherit all 310-ש״י camps called “something-Yesh-יש-310.” This is the secret of the verse,¹⁴Proverbs 8:21 “I have something-Yesh-יש-310 to bestow to those who love Me-Ohavai-אוהבי,” and as it also states,¹⁵Isaiah 41:8 “The offspring of Avraham who loved Me-Ohavee-אוהבי.” Understand this well.
