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.

And the angel of God said unto him,.... Instead of sitting down and partaking of the entertainment made for him, he bid him do as follows:

Take the flesh, and the unleavened cakes, and lay them upon this rock; not as a table to eat it from, but as an altar to offer it upon; and which rock and altar might be typical of Christ, who sanctities every gift, present, and offering of his people: this rock was undoubtedly in sight, and very probably the oak, under which they were, grew upon it, or at the bottom of it, where it was no unusual thing for oaks to grow,

Genesis 35:8, but it was upon the top of the rock that these were to be laid, where afterwards an altar was built, Judges 6:26

and pour out the broth; upon the flesh and cakes, and upon the rock also, which by bringing from his house must have been cool and it became cooler by being poured out, and cooler still by being poured upon a cold rock:

And he did so; he readily obeyed his orders; though he had reason to wonder he should have so ordered the food he brought for his entertainment to be thus made use of; perhaps he might expect that he intended to give him a sign, as he desired, and therefore the more readily, without any objection, complied with his order.
