Ibn Ezra on Deuteronomy 20:16/אבן עזרא על דברים כ׳:ט״ז

אלא תחיה. אסור שיאכילם או ישקם והכלל בימיהם היה חייב להמיתם אם יוכל ולא הזכיר הגרגשי כי הוא המעט והקטן שבהם:
1THOU SHALT SAVE ALIVE NOTHING. It is forbidden to give them food or drink. The general rule is that they were to kill them if possible. The latter applied to their days. Moses does not mention the Girgashites,17 for they were the least and the smallest among them.
