In Deu. 31:28, it is written,
Gather unto me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to record against them. (KJV)
Then, in Deu. 31:30, it is written,
And Moses spake in the ears of all the congregation of Israel the words of this song, until they were ended. (KJV)
Can we infer from these two scriptures that "all the elders of your tribes, and your officers" is [somtimes] equivalent to "all the congregation of Israel"?
For example, in Num. 15:36, it states that "all the congregation brought him without the camp, and stoned him with stones, and he died." Did hundreds of thousands of Israelites stone this one man with stones, or was it simply the [seventy] elders of the tribes and their officers?
