It does not follow that they had known him before, and recognized his voice, though it may be so. But the Hebrew equally bears the sense that they heard the voice of the Levite; and, attracted by it, went into the chapel Judges 18:18 where Jonathan was. They were probably just starting on their journey, but were still within the court or precincts of Micah's house. Micah had evidently not told them of his house of God, and his Levite. Their questions indicate surprise.

They knew the voice of the young man - They knew, by his dialect or mode of pronunciation, that he was not an Ephraimite. We have already seen (Judges 12:6 (note)) that the Ephraimites could not pronounce certain letters.

When they were by the house of Micah,.... At their inn, which might be next to it, or as they were passing by it:

they knew the voice of the young man the Levite; who had been in their country, and they had been in his company and conversation, and they knew the tone of his voice when they heard it; a particular brogue he might have. Abarbinel conjectures, that he was singing to Micah's idol, or multiplying his prayers before him:

and they turned in thither; into Micah's house, and into the apartment where the young man was:

and said unto him, who brought thee hither? they knew he was of Bethlehemjudah; they inquire therefore how he came there, who sent for him, and by what means he was brought to that place:

and what makest thou in this place? they knew he was a Levite, and that such an one had no business to minister but at the tabernacle, and therefore they inquire what was his employment here: and what hast thou here? to support himself with, what he had for his maintenance, or how he lived.

When they were at Micah's house and recognised the voice of the young Levite, i.e., heard his voice, and perceived form his dialect that he was not a native of these mountains, they turned aside there, sc., from the road into the house, near to which they rested, and asked him, "Who brought thee hither, and what doest thou at this place? what hast thou to do here?" When he told them his history ("thus and thus," lit. according to this and that; cf. 2 Samuel 11:25; 1 Kings 14:5), they said to him, "Ask God, we pray thee, that we may learn whether our way will be prosperous." בּאלהים שׁאל, used for asking the will of God, as in Judges 1:1, except that here the inquiry was made through the medium of the imitation of the ephod and the worship of an image. And he said to them, sc., after making inquiry of the divine oracle, "Go in peace; straight before Jehovah is your way," i.e., it is known and well-pleasing to Him (vid., Proverbs 5:21; Jeremiah 17:16).

When they were by the house of Micah, they knew the {c} voice of the young man the Levite: and they turned in thither, and said unto him, Who brought thee hither? and what makest thou in this place? and what hast thou here?

(c) They knew by his speech that he was a stranger there.

18:3 Knew - By the acquaintance which some of them formerly had with him.

17:7-13 Micah thought it was a sign of God's favour to him and his images, that a Levite should come to his door. Thus those who please themselves with their own delusions, if Providence unexpectedly bring any thing to their hands that further them in their evil way, are apt from thence to think that God is pleased with them.
