Judges 6:20

Pour out the broth - Libations were a very ancient form of offering (compare Genesis 35:14). The drink offerings of wine under the Levitical law were poured upon the altar Exodus 30:9. The pouring of the broth upon the rock was evidently of the nature of a libation. It might also, like the water poured by Elijah upon his sacrifice, make the miracle of the fire that consumed the sacrifice more apparent. (Compare 1 Kings 18:33.)
