Every Hair in Its Own Root
Hashem answered Iyov that He gives every hair its own root, and the Noam Elimelech sees in the hair a picture of the separation that baseless hatred brings.
Iyov said to Hashem, perhaps You have confused Iyov with oyev, an enemy. Hashem answered him out of the storm, and Chazal explain: I gave every hair its own root, for if two hairs drew from one root they would dim a person's sight; if I do not confuse one hair with another, would I confuse Iyov with oyev? The Noam Elimelech reads this answer as a key to Esav, who is called a hairy man. Each hair stands apart in its own root, and so hair hints at separateness, the baseless hatred of the time of the Second Beis HaMikdash, through which Esav gained his hold over the holy place. So when Yaakov sent his messengers, his holy words, to the land of Se'ir, whose letters spell sa'ir, hairy, he was working through speech to turn harsh judgments into compassion, in the very place whose name hints at the separation that gave Esav his hold.

Hashem keeps every hair in its own place, and still we are not meant to live as separate hairs. Think of one person in your family, shul or workplace with whom things have grown cold, for no reason you could clearly name. This week, take one small step across the gap: greet them first, ask after their family, or send a short message wishing them well. You do not need to settle everything. One warm word begins to undo baseless hatred.
