Ibn Ezra on Leviticus 8:26/אבן עזרא על ויקרא ח׳:כ״ו

אחלת מצה אחת. היא ככר לחם אחת ויתכן היות ככר משקל ואיננו כמשקל הכסף והזהב:
1ONE UNLEAVENED CAKE. The reference is to the one loaf (kikkar) of bread (Ex. 29:2s).38 usually refers to leavened bread. Hence I.E. explains that Ex 29:3 is to be understood as the one loaf of unleavened bread. I.E. comments thus so that there be no contradiction between the description of the consecration service in our chapter and the one in Exodus. It is possible that the term kikkar (loaf) refers to weight.39 of (un)leavened bread. This interpretation assumes that the term loaf would not be used in reference to unleavened bread. It is not the same weight as that of a kikkar (talent) of gold or silver.40
בוישם על החלבים. ולא הזכיר יותרת הכבד והכליות כי היותרת היא קטנה ופירוש המלה כמו מה יתרון לאדם והכליות הם על חלביהן כי לא יתכן שיקראו הכליות חלב רק האליה היא חלב:
2AND PLACED THEM ON THE FAT. Scripture does not mention the lobe41. of the liver and the kidneys, for the lobe was small. The meaning of yoteret (lobe) is similar to the meaning of the word yitron (profit)42 in What profit hath man (Eccles. 1:3).43 means the addition [to the liver]. The kidneys44 are offered with their fat,45 takes in the fat that is upon the kidneys. The kidneys were offered along with their fat because they are attached to it. for Scripture would not refer to the kidneys as fat.46 Only the fat tail is fat.47
