LXX Psalm 77:25
23 Yet he commanded the clouds from above, and opened the doors of heaven, 24 and rained upon them manna to eat, and gave them the bread of heaven. 25 Man ate angels' bread; he sent them provision to the full. 26 He removed the south wind from heaven; and by his might he brought in the south-west wind. 27 And he rained upon them flesh like dust, and feathered birds like the sand of the seas.
Wisdom of Solomon 16:20
18 At one time the flame was restrained, so that it might not consume the creatures sent against the ungodly, but that seeing this they might know that they were being pursued by the judgment of God; 19 and at another time even in the midst of water it burned more intensely than fire, to destroy the crops of the unrighteous land. 20 Instead of these things you gave your people food of angels, and without their toil you supplied them from heaven with bread ready to eat, providing every pleasure and suited to every taste. 21 For your sustenance manifested your sweetness toward your children; and the bread, ministering to the desire of the one who took it, was changed to suit everyone's liking. 22 Snow and ice withstood fire without melting, so that they might know that the crops of their enemies were being destroyed by the fire that blazed in the hail and flashed in the showers of rain;
Notes and References
"... The way food of angels is dealt with in the book of Wisdom (Wisdom of Solomon 16:20) should not be too easily linked with the traditions addressed above. The key to this, namely that the book of Wisdom calls manna the “food of angels,” is well-known for a long time now. The background surely can be found in Psalm 78:24‐25 and its Greek translation. In its relecture of Israel’s history this text reminds us of the miraculous feeding of the people in the desert. Psalm 78:24 assigns the manna as “bread from heaven” (Psalm 77:24 LXX: “bread of heaven”). Even more interesting is Psalm 78:25. The Hebrew text says “food of the noble ones” or “food of the strong ones.” The LXX renders it as (Psalm 77:25), “food of angels.” The Book of Wisdom thus follows here an interpretation of the manna narratives like the one presented in Psalm 77:24‐25 LXX. How much Wisdom of Solomon 16:20 and Psalm 77:24‐25 LXX are linked with each other can be seen with the help of Wisdom of Solomon 16:20 ..."
