For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns.
Transition to Judah. Supply mentally. All which (the foregoing declaration as to Israel) applies to Judah.
And Jerusalem - i:e., and especially the men of Jerusalem, as being the most prominent in Judea.
Break ... fallow ground - i:e., Repent of your idolatry and so be prepared to serve the Lord in truth (Hosea 10:12; Matthew 13:7; Matthew 13:22). The unhumbled heart is like ground which may be improved, being let out to us for that purpose; but which is as yet fallow, overgrown with weeds, its natural product.
