Side Curls

The long curls (peyot) that some Jewish men wear in order to observe Leviticus 19:27 (Do not cut the hair at the sides of your head") are a fairly recent tradition observed by some groups in the past few hundred years, mostly from Poland and Russia. Interestingly, one tradition links the side curls to a command in Leviticus 19:9-10:

When you reap the harvest of the land, do not reap to the very edges of your field or gather the
gleanings of your harvest. Do not go over your vineyard a second time or pick up the grapes that have fallen. Leave them for the poor and the alien.

Some think that by leaving the corners of their heads uncut, these Jewish men are reminding themselves and others of the importance of leaving the corners of their fields uncut -- in other words, of providing for the poor.
