“I have forsaken my house.” This is God speaking. The kingdom of Judah had so forsaken God that He in turn has forsaken Judah. In this context, God’s “house” is “the house of Israel and the house of Judah” (Jer. 11:17). He had left “his house,” and cast off his heritage, the people of Judah, and given what His soul dearly loved, i.e., His people, into the hand of her enemies. The enemies are called “her enemies” because God is using the figure of speech personification and portraying Judah as the woman He has loved.
[For more on the figure of speech personification, see commentary on Proverbs 1:20.]
