C. F. Keil and Franz Delitzsch on Judges 17:5-6

Jdg 17:5-6

His mother did this, because her son Micah had a house of God, and had had an ephod and teraphim made for himself, and one of his sons consecrated to officiate there as a priest. מיכה האישׁ (the man Micah) is therefore placed at the head absolutely, and is connected with what follows by לו: “As for the man Micah, there was to him (he had) a house of God.” The whole verse is a circumstantial clause explanatory of what precedes, and the following verbs ויּעשׂ, וימלּא, and ויהי, are simply a continuation of the first clause, and therefore to be rendered as pluperfects. Micah’s beth Elohim (house of God) was a domestic temple belonging to Micah’s house, according to Jdg 18:15-18. את־יד מלּא, to fill the hand, i.e., to invest with the priesthood, to institute as priest (see at Lev 7:37). The ephod was an imitation of the high priest’s shoulder-dress (see at Jdg 8:27). The teraphim were images of household gods, penates, who were worshipped as the givers of earthly prosperity, and as oracles (see at Gen 31:19). - In Jdg 17:6 it is observed, in explanation of this unlawful conduct, that at that time there was no king in Israel, and every one did what was right in his own eyes.
