18 "And say to the people, 'Purify yourselves, for tomorrow you will have meat to eat. You were whining, and the Lord heard you when you cried, "Oh, for some meat! We were better off in Egypt!" Now the Lord will give you meat, and you will have to eat it. 19 And it won't be for just a day or two, or for five or ten or even twenty. 20 You will eat it for a whole month until you gag and are sick of it. For you have rejected the Lord, who is here among you, and you have whined to him, saying, "Why did we ever leave Egypt?"'"

Commentary on Numbers 11:16-23
(Read Numbers 11:16-23)
Moses is to choose such as he knew to be elders, that is, wise and experienced men. God promises to qualify them. If they were not found fit for the employ, they should be made fit. Even the discontented people shall be gratified too, that every mouth may be stopped. See here, I. The vanity of all the delights of sense; they will cloy, but they will not satisfy. Spiritual pleasures alone will satisfy and last. As the world passes away, so do the lusts of it. 2. What brutish sins gluttony and drunkenness are! they make that to hurt the body which should be its health. Moses objects. Even true and great believers sometimes find it hard to trust God under the discouragements of second causes, and against hope to believe in hope. God here brings Moses to this point, The Lord God is Almighty; and puts the proof upon the issue, Thou shalt see whether my word shall come to pass or not. If he speaks, it is done.
