Is Israel a servant? - Is he a slave purchased with money, or a servant born in the family? He is a son himself. If so, then, why is he spoiled? Not because God has not shown him love and kindness; but because he forsook God, turned to and is joined with idols.
It was Israel‘s glory to be Yahweh‘s servant Jeremiah 30:10, and slaves born in the house were more prized than those bought with money as being more faithful Genesis 14:14. Cannot Yahweh guard His own household? How happens it that a member of so powerful a family is spoiled? In the next verse the prophet gives the reason. Israel is a runaway slave, who has deserted the family to which he belongs by right of birth, and thereby brought upon himself trouble and misery.
