Where does the Bible say he had a beard?
Isaiah 50:6
There’s a more specific reference among the prophets about them plucking his beard, which I couldn’t find right now, but Leviticus 19 forbids Jewish men from trimming their beards.
Found it! “I gave my back to those who strike, and my cheeks to those who pull out the beard; I hid not my face from disgrace and spitting.” (Isa 50:6)”
