Komentaryong Sumisipi para sa Mga Awit 78:31

והיה לכם לזרא, they will eat so much of it that that it will cause an excess which in turn will produce sickness. This is what Assaph in Psalms 78,31 spoke about.

הבשר עודנו בין שניהם, “while the meat was still between their teeth, before it had been chewed, etc.;” to the question of why G–d waited this long before displaying His anger, the answer is that if He had reacted angrily sooner, the people would have interpreted His anger as proof that He was unable to meet their requests. Once He had proved that He could provide not only what they had asked for but more, He reacted with the anger that He had withheld up to then. We find an interesting verse in Psalms 78.31:ויהרוג במשמניהם, “He killed the healthy, fat ones among them.” The psalmist considers that the healthy young men amongst the people at that time, were more guilty than any other section of the people as they had lacked absolutely nothing, as testified to by their continued health and vitality even in the desert. The Torah describes some people dying while not even having swallowed the meat yet, others are described as eating from it for a whole month. How do we understand this? The moral level of different Israelites varied. The ones on the lowest level did not even get to swallow it, whereas those on higher levels died at a time appropriate to their respective moral standing.
