"I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting."
Isaiah 50:6
Interesting that while the Gospels record Jesus as being smitten and spat upon, it doesn't mention His beard being plucked.
Some obviously consider the silence as evidence Jesus had no beard. I side with Isaiah's prophecy even though the NT Gospels are silent.
