'Furrows' in the Bible

They have spoken empty (disingenuous) words,Swearing falsely to make covenants [they intend to break];Therefore, judgment springs up like poisonous weeds in the furrows of the field.

Is there wickedness (idolatry) in Gilead?Surely the people there are worthless.In Gilgal [they defy Me when] they sacrifice bulls,Yes, [after My judgment] their [pagan] altars are like the stone heapsIn the furrows of the fields.
