Midrash su Genesi 37:15

And Jacob said to him: “Go now, see whether it is well with thy brethren … and he came to Shechem (ibid. 37:14).¹B. Sanhedrin 10:29. This place had previously been designated for punishment. Dinah was dishonored in Shechem, Joseph was sold in Shechem,²Dothan, the place where Joseph was sold, was in the vicinity of Shechem; in addition, tradition maintains that he was buried in Shechem. and David’s kingdom was divided at Shechem: Jeroboam built Shechem in the hill country of Ephraim (I Kings 12:25). And a certain man found him (Gen. 37:15). The man referred to is none other than (the angel) Gabriel, as it is said: The man Gabriel (Dan. 9:21). And they saw him from afar … and they took him, and cast him into the pit (Gen. 37:18, 24). The pit was empty of water, but it contained snakes and scorpions. What did Reuben do? He remained upon one of the hills nearby in order to rescue Joseph during the night. However, the nine other brothers stayed together in another place, all in agreement that he should die.

"straying": "straying" in all instances connotes outside of the boundary. Though there is no proof for this, there is support for it in (Genesis 37:15) "and, behold, he was straying in the field."

(Gen. 37:15:) THEN A MAN FOUND HIM, < i.e., > an angel.³⁰Cf. Gen. R. 84:14.

"A man found him, and behold! He was blundering in the field: Rabbi Yannai said: He [Joseph] was met by three angels for scripture says, "A man found him" (Gen. 34:15); "and the man asked him"; and "the man said" (Gen. 34:17). "They have gone from here" - from the characteristics of the Place. "And they saw him far off"(Gen. 34:18): They said, 'Let us kill him by inciting the dogs against him.' "And they said one to another behold the dreamer comes"(Gen. 34:19): the rabbis said, “they exclaimed, Behold he is coming wrapped in his dreams”. Rabbi Levi said, “[they said] this one will ensnare us into serving foreign overloads.” "Come now therefore and let us slay him"(Gen. 34:20): The Holy One of Blessing said to them, “You say ‘We shall see’ and I say ‘We shall see’. Indeed "we shall see whose words will be fulfilled." (Jer. 34:28)
