Here is the definition of “beard” in the Bible Dictionary.
Beard. Regarded by the Jews as of great importance (whereas Egyptians always shaved); the trimming of the corners was forbidden (Lev 19:26-28), such a practice being a mark of idolatry (Jer 41:5). See also 1 Sam 21:13; 2 Sam. 10:4. A leper was compelled to shave (Lev 14:9).
Do you think current views about beards make us spiritual lepers? Is it a sign of idolatry?
