Matthew Poole and continuators on Judges 17:4

4 Yet he restored the money unto his mother , and his mother took two hundred shekels of silver , and gave them to the founder, who made there▪ of a graven image, and a molten image, and they were in the house of Micah.

Though his Mother allowed him to keep it, yet he persisted in his resolution to restore it, that she might dispose of it as she pleased; and did actually restore it, as was said before; and now confirms the former Restitution, and therefore is twice said to restore it.

Reserving 900 Shekels either for the Ephod and Teraphim, or for other things relating to this Worship: or for her own private use; being, it seems, cooled in her first Zeal, and willing to have as cheap a Religion as she could, as also her Son Micah was, Iudg. 17. 10.

Made them, either, First, of that Matter: Or, Secondly, for that money.
