Ibn Ezra on Deuteronomy 33:15/אבן עזרא על דברים ל״ג:ט״ו

אומראש. הטעם וממגד ראש הררי קדם:
1AND FOR THE TOPS. This means and for the precious things that grow on the tops of the ancient hills.128 from the previous verse also applies here. Thus u-merosh harere kedem (and for the tops of the ancient mountains) is to be read as if written u-mi-meged rosh ha-rere kedem (and for the precious things that grow on the tops of the ancient mountains).
בגבעות עולם. כפול:
2THE EVERLASTING HILLS. Scripture repeats itself.
