Judges 6:19-20

19Then Gideon went in and prepared a kid and matzot from an ephah of flour. He put the meat in a basket and the broth in a pot, and brought them out to Him under the terebinth and presented them.

20Then the angel of God said to him, “Take the meat and the matzah and lay them on this rock, and pour out the broth.” So he did so.
