וַיֹּ֤אמֶר יְהוָה֙ אֶל־אַבְרָ֔ם לֶךְ־לְךָ֛ מֵאַרְצְךָ֥ וּמִמּֽוֹלַדְתְּךָ֖ וּמִבֵּ֣ית אָבִ֑יךָ אֶל־הָאָ֖רֶץ אֲשֶׁ֥ר אַרְאֶֽךָּ׃
Yang Mahakekal berfirman kepada Abram, “Pergilah engkau dari negerimu, dari kaum kerabatmu, dan dari rumah ayahmu, ke negeri yang akan Kutunjukkan kepadamu.”
Midbar Kedemot
10) Our father Abraham, peace be upon him: The Holy One, blessed be He, compared him to rain. Accordingly, the words Abram, "Surely go" [Avram, "Lekh lekhah"] (Genesis 12:1) is the numerical equivalent [gematria] of rain [geshem]. Just like rain is enclosed in the clouds, and no one knows its nature, but when it falls to the earth, everyone benefits from it; so too [Abraham's] nature did not go out into the world when he was in his [previous] place. And just like rain brings blessing to the world, so too you — and you shall be a blessing (Genesis 12:2). And Rabbenu Ephraim also wrote at length [about this] in his commentary. And it is possible even to say that Avraham is the numerical equivalent of precipitation [matar] when being inclusive [adding the word itself to the count, a tool used when the equivalent is off by one].
