Charles Ellicott Commentary Judges 6:20

"And the angel of God said unto him, Take the flesh and the unleavened cakes, and lay them upon this rock, and pour out the broth. And he did so." — Judges 6:20 (ASV)

The angel of God. —Only in this chapter is he called “the angel of Elohim” and not “of Jehovah.”

Upon this rock. —Rather, upon that crag. The living rock (Exodus 20:22) served well as an altar.

Pour out the broth. —Compare Genesis 35:14; Exodus 30:9; 1 Kings 18:34. In the first of these instances the “drink offering” is used as a libation; in the last Elijah pours the sea-water on the sacrifice, to show the impossibility of any deception. In 2 Maccabees 1:20-36 Nehemiah pours the “thick water,” called “Naphthai,” on the sacrifice, and when the sun shone “there was a great fire kindled, so that every man marvelled.”
