וַיֹּ֤אמֶר יַעֲקֹב֙ כַּאֲשֶׁ֣ר רָאָ֔ם מַחֲנֵ֥ה אֱלֹהִ֖ים זֶ֑ה וַיִּקְרָ֛א שֵֽׁם־הַמָּק֥וֹם הַה֖וּא מַֽחֲנָֽיִם׃ (פ)
야곱이 그들을 볼 때에 이르기를 이는 하나님의 군대라 하고 그 땅 이름을 마하나임이라 하였더라
Tractate Soferim
"And Lord of lords" (ibid.) - the first 'Lord' is holy, the second isn't. "God of Abraham" (Genesis 31:53) is holy, "God of Naḥor" (ibid.) isn't. "God do not curse" (Exodus 22:27) could be holy or not - Rabbi Shimon says, holy. "For seeing your face is like seeing the face of God" (Genesis 33:10) - this is definitely not holy. "Camp of God" (Genesis 32:2) - this is definitely holy.
Berakhot
Rab said : He beheld our father Jacob ; for it is written, "And Jacob said when he beheld them" (Gen. xxxii. 3). Samuel said : He beheld the ashes of [the sacrifice substituted for] Isaac ; as it is said, "God will provide Himself the lamb" (ibid. xxii. 8).
