摩西再三查問那隻作贖罪祭的公山羊，看哪，牠已經被焚燒了；摩西就向亞倫存留下來的兒子以利亞撒和以他瑪發怒，說：
Rashi
ויאמר אלעזר הכהן וגו׳ AND ELEAZAR THE PRIEST SAID etc. — Because Moses fell into anger (Numbers 31:14) he fell into error: there escaped him the laws concerning the removal of uncleanness absorbed by vessels which have contained the food of heathens. This, too, do you find was the case on the eighth day of the installing of the priests, as it is said, (Leviticus 10:16) “And Moses was angry with Eleazar and Ithamar”, — he fell into anger, he fell into error (cf. 10:16 that he made an error regarding the שעיר החטאת which Aaron refused to eat). Similarly, also, when he said, (Numbers 20:10, Numbers 20:11) “Hear, now, ye rebels”, … “he smote the rock”; it was through his anger that he made the mistake (Sifrei Bamidbar 157:9; cf. Pesachim 66b).
