Angels' Food

Concise Bible Dictionary:

These words are figurative. Psalm 78:2424And had rained down manna upon them to eat, and had given them of the corn of heaven. (Psalm 78:24) speaks of “the corn of heaven,” and Psalm 78:2525Man did eat angels' food: he sent them meat to the full. (Psalm 78:25) is better translated "man did eat the bread of ‘the mighty:’ he sent them food to the full." It doubtless refers to the manna.
