What does the Bible say about the iniquity of Ephraim?

In the book of Hosea, Ephraim is frequently mentioned as a type of Israel and serves as an illustration of the waywardness of God’s people. Ephraim’s iniquity is characterized by spiritual adultery, as he is described as joined to idols and committed to whoredom. This reflects a broader reality: though God's children may stray, His grace abounds, leading to their eventual restoration and reconciliation. In Hosea 11:1-4, we see God's tender love for Ephraim, showcasing the dichotomy of rebellion and the promise of divine restoration and mercy.
