Starting a new thread may be appropriate; however, the answer is pretty simple: the Lord doesn’t take kindly to young persons disrespecting their elders, and especially not a Prophet, and there are consequences if they do. Keep in mind that these were not necessarily “children” - that’s an interpretation thing. In Jewish custom, “children” were anyone not “of age,” and that age was fairly advanced. Also, rebellious children (teenagers) who did not comply were stoned by their parents in this society.
The lesson here is, “Don’t disrespect your elders or the Lord will send a bear to eat you!”
