For the time has come for judgment to begin at the house of God. If it begins first with us, what will happen to those who don't obey the Gospel of God?
At the house of God - Benson, Bloomfield, and many others, suppose that this refers to the Jews, and to the calamities that were to come around the temple and the holy city about to be destroyed. But the more obvious reference is to Christians, spoken of as the house or family of God. There is probably in the language here an allusion to Ezekiel 9:6; “Slay utterly old and young, both maids, and little children, and women; and begin at my sanctuary.” Compare Jeremiah 25:29. But the language used here by the apostle does not denote literally the temple, or the Jews, but those who were in his time regarded as the people of God - Christians - the church. So the phrase (בּית יהוה bēyt Yahweh) “house of Yahweh” is used to denote the family or people of God, Numbers 12:7; Hosea 8:1. Compare also 1 Timothy 3:15 and the note on that verse. The sense here is, therefore, that the series of calamities referred to were to commence with the church, or were to come first upon the people of God. Schoettgen here aptly quotes a passage from the writings of the Rabbis: “Punishments never come into the world unless the wicked are in it; but they do not begin unless they commence first with the righteous.”
