Shared ground
This passage presents two linked answers to a crisis: Moses is overwhelmed, and the people are demanding food. Yahweh addresses the leadership problem by expanding shared responsibility through seventy recognized elders, already known as leaders and officers (explicit in vv. 16–17). He addresses the food problem by promising meat “tomorrow” and then specifying an excessive duration (vv. 18–20).
God’s action is both relational and administrative: he will meet Moses at the tent of meeting, speak with him, and empower others so Moses does not carry the community alone (vv. 16–17). At the same time, God interprets the people’s craving and weeping as more than hunger: they portrayed Egypt as better and, in doing so, “rejected” Yahweh who is among them (v. 20).
Where interpretation differs (only where needed)
1) What it means to “take of the Spirit” on Moses and put it on the elders (v. 17). Some read this as a real empowerment for leadership that does not reduce Moses, like lighting many lamps from one flame. Others think the wording implies a transfer that, in some sense, reallocates Moses’ unique endowment—without necessarily denying Moses’ continuing role.
2) Whether the meat promise is mainly provision or mainly discipline (vv. 18–20). Many read it as both: God gives what was demanded, but in a way that exposes the demand’s disordered nature (“loathsome,” “come out at your nostrils”). Others emphasize one side: either God’s generosity in meeting needs, or God’s severe response to rejection and nostalgia for Egypt.
3) How literal the “nostrils” language is (v. 20). Some take it as intentionally vivid exaggeration to describe extreme excess and disgust. Others expect it to correspond more directly to a physical outcome in the story’s continuation, while still recognizing the rhetorical punch.
Why the disagreement exists
The text uses concrete actions (gathering elders; eating for a month) alongside highly charged language (“take of the Spirit”; “come out at your nostrils”; “sanctify yourselves”). Those phrases can be read either more literally or as strong, image-heavy speech. Also, the passage contains both mercy (shared leadership; meat given) and rebuke (they “rejected” Yahweh), and interpreters weigh those emphases differently.
What this passage clearly contributes
It portrays Yahweh as directly involved in Israel’s governance and sustenance: he orders a leadership structure and supplies food on a set timetable (explicit). It also defines the deeper issue behind the complaint: longing for Egypt and framing the exodus as a mistake is treated as rejecting Yahweh’s presence among them (explicit in v. 20). The passage sets up a theology of shared leadership under God’s Spirit and a warning that desires expressed as distrust can receive an answer that becomes judgment (inference drawn from the stated “loathsome” outcome and the stated reason).
