Isaiah 50:6 says that He had a beard, is the translation in dispute?
I’ve always hated depictions of Him with long hair. Not only does it directly ignore Paul’s words in 1 Corinthians 11:14 (God wouldn’t put that in the Bible if Jesus had long hair, and as far as I’m aware the translation to English of that verse isn’t particularly controversial), it also makes Him look like a sissy liberal, which He is NOT.
“long” is relative. Some natural hair for women is extremely long. I would tend to go with historical Jewish tradition for the time before making any judgments. I love Marine high and tight cuts, but I grew up in the 60’s and also like long hair. I abhor dreadlocks, or matted hair. Whatever looks good for the face.
