19 So Manoah took the young goat with the meal offering, and offered it on the rock to Yahweh: and (the angel) did wondrously, and Manoah and his wife looked on.

The angel did wondrously - He acted according to his name; he, being wonderful, performed wonderful things; probably causing fire to arise out of the rock and consume the sacrifice, and then ascending in the flame.
So Manoah took a kid with a meat offering, and offered [it] upon a rock unto the LORD: and [the angel] did (i) wondrously; and Manoah and his wife looked on.
(i) God sent fire from heaven to consume their sacrifice, to consume their faith in his promise.
So Manoah took a kid with a meat offering,.... The kid which he proposed to make an entertainment with, for the man of God, he took him to be, he fetched and brought for a burnt offering, at the hint which the angel had given him, and joined to it a meat offering, as was usual whenever burnt offerings were made; see Numbers 15:3,
and offered it upon a rock unto the Lord; for though Manoah was not a priest, nor was this a proper place for sacrifice; high places were now forbidden, and only at the tabernacle in Shiloh were offerings to be brought; yet all this was dispensed with, and Manoah was justified in what he did by the warrant of the angel, Judges 13:16. The rock was probably near the place where this meeting of Manoah and his wife with the angel was, and where the discourse between them passed; and which served instead of an altar, and on which Manoah sacrificed, not to idols, but to the true Jehovah, as the angel directed:
and the angel did wondrously; agreeably to his name, which was "Wonderful", Judges 13:18 or "he, Jehovah, did wondrously" for this angel was no other than Jehovah the Son. The instance in which he did wondrously was, as Kimchi observes, by bringing fire out of the rock, which consumed the flesh of the kid, and the meat offering; and so Josephus (q) says, that he touched the flesh with a rod he had, and fire sparkled out, and consumed it with the bread, or meat offering; just in the same manner as the angel did with the kid and cakes that Gideon brought, Judges 6:21.
and Manoah and his wife looked on; to see either fire come down from heaven, or spring up out of the rock, which consumed the sacrifice, and showed the Lord's acceptance of it, and also the angel's ascending in it, as follows.
(q) Ut supra. (Antiqu. l. 5. c. 8. sect. 3.)
Manoah then took the kid and the minchah, i.e., according to Numbers 15:4., the meat-offering belonging to the burnt-offering, and offered it upon the rock, which is called an altar in Judges 13:20, because the angel of the Lord, who is of one nature with God, had sanctified it as an altar through the miraculous acceptance of the sacrifice. לעשׁות מפלא, "and wonderfully (miraculously) did he act" (הפליא followed by the infinitive with ל as in 2-Chronicles 26:15). These words form a circumstantial clause, which is not to be attached, however, to the subject of the principal clause, but to ליהוה: "Manoah offered the sacrifice to the Lord, whereupon He acted to do wonderfully, i.e., He performed a wonder or miracle, and Manoah and his wife saw it" (see Ewald, Lehrb. 341, b., p. 724, note). In what the miracle consisted is explained in Judges 13:20, in the words, "when the flame went up toward heaven from off the altar;" that is to say, in the fact that a flame issued from the rock, as in the case of Gideon's sacrifice (Judges 6:21), and consumed the sacrifice. And the angel of the Lord ascended in this flame. When Manoah and his wife saw this, they fell upon their faces to the earth (sc., in worship), because they discovered from the miracle that it was the angel of the Lord who had appeared to them.
Meal - offering - Which were generally joined with the chief sacrifices. A Rock - The angel's presence and command being a sufficient warrant for the offering of sacrifice by a person who was no priest, and in a place otherwise forbidden.
