Judges 13:20

“For it came to pass, when the flame went up towards heaven from off the altar, etc.] That is, from the rock, which served instead of an altar, and from whence perhaps the fire sprung which consumed both the burnt offering and the meat offering, the flame of which went up to heaven; this rock or altar having no covering, but was “sub dio”, open to the heavens: that the angel of the Lord ascended in the flame of the altar; making use of the smoke, as Josephus f273 says, as a vehicle in which he openly went up to heaven: and Manoah and his wife looked on it; on the flame and smoke, and the angel in it as he ascended; just as the disciples of Christ looked steadfastly on him as he went up to…”

“The altar - That is, from that part of the rock which served instead of an altar, upon which the sacrifice was laid. Ascended - To manifest his nature and essence to be spiritual. Fell - Partly in reverence to that glorious presence manifested in so wonderful a manner: and partly, out of a religious horror and fear of death; for the prevention thereof they fell down in way of supplication to God. Judges 13:23”
