roasted

This word usually refers to cooking food over an open fire or in a pan, not to burning completely. Possible meanings are 1) this is a euphemism. Alternate translation: "burned to death" or 2) the king's men attached them to poles over the fire close enough that the fire would slowly kill them but far enough away that it would not totally consume their bodies. (See: rc://en/ta/man/translate/figs-euphemism)
