The great sacrificial feast hosted by God is defined by an overwhelming abundance of meat and blood, providing for the guests far beyond what is typical. The primary approach among commentators is that the imagery highlights the massive scale of the food and drink served, which is more than enough to completely satisfy hunger and bring about a state of drunkenness [מלבי״ם].
The food provided is not ordinary; it represents the absolute best and fattiest portions of meat available [ביאור שטיינזלץ]. Guests will consume these rich portions until they are entirely full and satisfied [מצודת דוד].
The drinking at this feast is equally extraordinary. There will be a staggering amount of blood present at the event, far exceeding any normal necessity. Through poetic language, the blood is compared to intoxicating wine, illustrating that the guests will drink from it until they become completely drunk [מצודת דוד].
