Why did God give us facial hair?

Significance of Beards in Israelite Culture

All men among the Israelites were instructed by God to grow beards, as indicated in the commandment: “You shall not round off the hair on your temples or mar the edges of your beard” (Leviticus 19:27). Beards served as a prominent symbol of masculinity, providing a clear visual distinction between men, boys, and women at a glance.
