Exodus 16:17-18

Manna from Heaven.

Behold, I am about to rain bread from heaven for you, and the people shall go out and gather a day’s portion every day, that I may test them, whether they will walk in my law or not.

Giovanni Battista Tiepolo (1696–1770) - The Hebrews Gathering Manna in the Wilderness (c. 1740), oil on canvas, 92 x 67 cm. This amazing painting appears to be a study for a later work, The Gathering of the Manna (1738-42). The study buzzes with energy missing from the latter.
