Hear this word that the LORD has spoken against you, O children of Israel, against the whole family which I brought up from the land of Egypt, saying,
All Commentaries on Amos 3:1 Go To Amos 3
Cyril of Alexandria
AD 444
The verse could be taken as addressed to the whole of Israel, not citing Judah and Ephraim separately, but as though addressing a unit comprising every tribe, since every tribe of Israel was led out of the land of Egypt.
