“For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns.”
King James Version (KJV)
4:3 For - The Lord turns now his speech from Israel to Judah. Break up - Prepare your hearts by making them soft, tender, and pliable, fit to embrace my word. A metaphor taken from plow - men. Thorns - Rid your hearts and hands of what may hinder you of embracing my word.
