The threat makes one uncomfortable. However, we would be wrong to read any sexuality or sadism into it. For the writer continues in this verse by saying, I will make her as in the day she was born.
Later he adds that the provisions of wool and flax were to cover Israel’s nakedness (Hosea 2:9). Thus the image of nakedness suggests helplessness. Israel will become needy like a new-born child, stripped of God’s provision and protection.
As Hubbard1 notes, ridicule or embarrassment may be implied (Ezekiel 16:37; Ezekiel 23:10). Thus Dearman2 says, the stripping of Gomer is likely a metaphor for the humiliating punishment that Israel will suffer in the historical process rather than her literally being forced naked from the home.
In keeping with what is to follow in Ezekiel 16:37, God is threatening to withdraw his covenant blessings from Israel. This will highlight both that he was always the source (Hosea 2:5, Hosea 2:8) and that the Baals were unable to protect Israel (Hosea 2:10). Ortlund3 says that economic hardships will make it clear that her lawful husband has directly confronted Israel and exposed her futile love affair with the Baals.
3 lest I strip her naked and make her as in the day she was born, and make her like a wilderness, and make her like a parched land, and kill her with thirst.
