Ibn Ezra on Deuteronomy 4:1/אבן עזרא על דברים ד׳:א׳

אמלמד אתכם לעשות. כי עיקר הלמוד לעשות המצות:
1WHICH I TEACH YOU, TO DO THEM. The main purpose of study is the observance of the commandments.
בלמעז תחיון. כי עובדי פעור נשמדו:
2THAT YE MAY LIVE. For those who worshipped pe’or were destroyed.1
גוירשתם. בעבור שנח ונעלם היו״‎ד בשבר הוי״‎ו נשבר עי״‎ן הפעל ואפס על משקלו:
3AND POSSESS. The middle root letter of the verb vi-yerishtem (and possess)2. The root of vi-yerishtem is yod, resh, shin. is vocalized with a chirik because the yod is silenced and made invisible by the chirik beneath the vav.3. Hence I.E.’s comment. There is no other word that is similarly vocalized.
