Ibn Ezra on Deuteronomy 25:13/אבן עזרא על דברים כ״ה:י״ג

אבכיסך. מקום למאזנים או יוציא מן הכיס בדרך רמאות והראשון הוא נכון והעד כיס אחד יהיה לכלנו משקל אחד. ומגזרת תכוסו על השה ואם הוא משורש אחר ורבים פירשו כמו חריט ואין צורך:
1IN THY BAG.60. Where you place the scales.61 (bag) is the name of a receptacle where the scales are kept. Or, do not deceitfully take the weights from the bag.62 The first interpretation is correct. The proof text is, Let us all have one hag (kis)63 (Prov. 1:14), the meaning of which is, one scale.64 (Prov. 1:14) is, let us all have one scale, for let us all have one bag makes no sense in this context. The word kis (bag) is related to the word tachossu (ye shall make your count)65 means you shall apportion. A person uses scales to measure the weight of portions. See I.E. on Ex. 12:4 (Vol. 2, p. 219). in ye shall make your count for the lamb (Ex. 12:4) even though tachossu comes from a different root.66 comes from the root caf, vav, samekh. Tachossu comes from the root caf, samekh, samekh. Many explained the word kis to mean a pouch.67 (a cloth into which an object is placed). In this case kis refers not only to a receptacle for scales but to any bag or purse. There is no need for this interpretation.
