Комментарий к Шмот 39:26

פעמון ורמון, פעמון ורמון, a bell and a pomegranate, a bell and a pomegranate (alternating). The Torah had to write this as otherwise one could have hung two or three bells between each pomegranate or vice versa and this would still have corresponded to the definition "between the pomegranates." The first statement teaches that one pomegranate and one bell should alternate, i.e. there should not be two bells between a set of pomegranates. The second statement is to prohibit the reverse, i.e. two pomegranates between each set of bells.
