The expression, “go up...go up,” is held by many scholars to reflect the wish of these young lads that the prophet go ahead and ascend, i.e., leave the earth, that they might be rid of him. Also, the taunt, “thou bald head,” was likely a reproach. Old Testament scholar John Whitcomb has suggested that this was an expression “of extreme contempt". They were pronouncing a divine curse upon him, for which baldness was often the outward sign.
So is this a literal or allegorical reading of the Bible?
