What does it mean to “mar the corners of thy beard”?
Lev 19:27 Ye shall not round the corners of your heads, neither shalt
thou mar the corners of thy beard.
This law was given to the Israelites to prevent them from following and imitating pagan practices in trimming their beards ,facial and head hair. This did not necessarilly mean that the Israelites could not trim their beards or hair at all. (2 Sam.19:24)

who cut their hair short at the temples. I will bring disaster against
them from every direction,” says the Lord."
