What does the Bible say about Ephraim in Zechariah?

In Zechariah 10, Ephraim is depicted as a people blessed by God, having originally enjoyed His favor and presence symbolized by their proximity to the tabernacle. However, their story also reflects a downward spiral into idolatry and self-centeredness, paralleling humanity's fall in Adam. Yet, God promises restoration, saying He will redeem and gather them again, indicating His unchanging covenant love and mercy, showcasing the reality of grace in Christ as the means of true salvation.
