Adam Clarke on Psalms 78:25

Man did eat angels' food - לחם אבירים אכל איש lechem abbirim achal ish, "Man did eat the bread of the mighty ones;" or, each person ate, etc. They ate such bread as could only be expected at the tables of the rich and great, the best, the most delicate food. How little did this gross people know of the sublime excellence of that which they called light bread, and which they said their soul loathed; Num 21:5! It was a type of Jesus Christ for so says St. Paul: "They all ate the same spiritual meat, and drank the same spiritual drink," etc., 1Cor 10:3, 1Cor 10:4. And our Lord calls himself "the bread that came down from heaven, that giveth life unto the world," Joh 6:31-35 : but a Jew sees nothing but with the eyes of flesh. It is true their doctors or rabbins are full of allegories, mysteries, and conceits; but they are, in general, such as would disgrace the Cabinet des Fees, and would not be tolerated in the nursery. O, how thick a veil hangs over their gross and hardened hearts.
