16 This is the thing which the Lord hath commanded, Gather of it every man according to his eating, an omer for every man, according to the number of your persons; take ye every man for them which are in his tents.
17 And the children of Israel did so, and gathered, some more, some less.
18 And when they did mete it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating.
Now the Lord gave very specific directions that every man was to gather a certain amount of food, related to the size of his household. If a man had ten people in his household, he would gather ten omers’ worth of manna, if he had two people he would gather two omers’ worth. An omer was an Old Testament measurement of volume, understood to be roughly equivalent to two quarts.
And, miraculously, this measurement turned out to be perfect for all people. There was neither excess nor want, so long as one adhered to the measurement given by God. This seems a miraculous thing, that men, women, and children of all different sizes and weights would be sustained by the same equal measure. Of course, the existence of the manna in the first place was an even greater miracle, so maybe that isn’t so surprising.
Once again, there is clear symbolism in this. God knows our needs perfectly, and He prescribes to us exactly what is right. He not only gives us the sustenance that our souls need, He gives just the right amount with no lack and no waste. I have personally seen little miracles in my life, always providing just the right help at just the right time. An unexpected one-time financial boost, a perfectly directed prompting to my spiritual leader, a window of time to get to know a dear friend before he passed away, I see all of these as miracles from heaven, each perfectly portioned to my need.
