Hosea 7:9

Foreign alliances had sapped Ephraim’s strength rather than adding to it, but the Israelites were ignorant of this. They thought they were as strong as ever. Tribute payments to allies constantly drained the nation’s wealth and weakened its economy (cf. 2 Kings 15:19-20; 2 Kings 17:3). Israel was unaware of its real condition, as when a person’s hair becomes gray but he does not notice it. Others can sense the approach of death, but he does not. Israel was dying in the late 730s and early 720s, but its own people did not know it.
