"And a certain man found him, and behold, he was wandering in the field. And the man asked him, saying: ‘What seekest thou?' And he said: ‘I seek my brethren. Tell me, I pray thee, where they are feeding the flock'" (Genesis, 37).
A man "wandering in the field" refers to a place from which the crop of the field to sustain the world should spring. And the works of the field are plowing, sowing, and reaping. It is said about that: "They that sow in tears shall reap in joy," and this is called "a field which the Lord has blessed."
A person wandering in the field refers to the degree of "man" who strays from the path of reason, who does not know the real way, which leads to the place he should reach, as in "an ass wandering in the field." And he comes to a state where he thinks that he will never achieve the goal he should achieve.
"And the man asked him, saying: ‘What seekest thou?'" meaning, "How can I help you?" "And he said: ‘I seek my brethren.'" By being together with my brothers, that is, by being in a group where there is love of friends, I will be able to mount the trail that leads to the house of God.
This trail is called "a path of bestowal," and this way is against our nature. To be able to achieve it, there is no other way but love of friends, by which everyone can help his friend.
"And the man said: ‘They are departed hence.'" And Rashi interpreted that they had departed themselves from the brotherhood, meaning they do not want to bond with you. This, in the end, caused Israel's exile in Egypt. And to be redeemed from Egypt, we must take it upon ourselves to enter a group that wants to be in love of friends, and by that we will be rewarded with exodus from Egypt and the reception of the Torah.
