David Hill in the New Century Bible Commentary notes that this might be a reference to the hiding of the Hanukkah lamp to protect it from desecration.

[2] Eduard Schweizer notes that at this time almost all houses would have only had one room, so a single lamp is all that would have been needed to shine on all inhabitants.

[4] Ambrose: And therefore let none shut up his faith within the measure of the Law, but have recourse to the Church in which the grace of the sevenfold Spirit shines forth.

[4] Hilary of Poitiers: He means not that we should seek glory of men, but that though we conceal it, our work may shine forth in honour of God to those among whom we live.
