וַיֹּאמַ֑ר אֲדֹנָ֣י יֱהוִ֔ה בַּמָּ֥ה אֵדַ֖ע כִּ֥י אִֽירָשֶֽׁנָּה׃
Lalu berkatalah Abram: “Ya Tuhan Yang Mahakekal, dengan apakah aku dapat mengetahui bahwa aku akan mewarisinya?”
The Midrash of Philo
Why does he say, "Lord, by what shall I know that I shall inherit it?"(Genesis 15:8).
Who is the Heir of Divine Things
[100] But it is not enough for the lover of wisdom to have high hopes and vast expectations through the oracular promises. If he does not know in what way he will attain the succession of the heritage, it irks him greatly; so thirsty is he for knowledge and insatiate of it. And therefore he asks, “Master, by what shall I know that I shall inherit it?” (Gen. 15:8).
