Ibn Ezra on Genesis 24:6/אבן עזרא על בראשית כ״ד:ו׳

אכל השמר מלעיל מלשון שמירה. ואשר מלרע לשון שמרים, כמו "השמר והשקט" (ישעי' ז ד) כטעם "ושקט הוא על שמריו" (ירמי' מח יא):
1[BEWARE.] When the word hishamer (beware) is penultimately accented it is related to the word shemirah (watching, guarding).13 is penultimately accented it means be on guard, beware. This is the usual meaning of hishamer in Scripture. Cf. Deut. 8:11. However, when it is ultimately accented it is related to the word shemarim (lees).14 is accented on the last syllable. Compare, hishamer (keep calm) in Keep calm (hishamer), and be quiet (Is. 7:4), which has the same basic meaning as shemarav (his lees) in And he hath settled on his lees (shemarav) (Jer. 48:11).
