C. F. Keil and Franz Delitzsch on Judges 13:19-20

Jdg 13:19-20

Manoah then took the kid and the minchah, i.e., according to Num 15:4., the meat-offering belonging to the burnt-offering, and offered it upon the rock, which is called an altar in Jdg 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 2Ch 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 Jdg 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 (Jdg 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.
