Therefore it shall come to pass, that as all good things are come upon you, which the LORD your God promised you; so shall the LORD bring upon you all evil things, until he have destroyed you from off this good land which the LORD your God hath given you. So shall the Lord bring upon you all evil things - His faithfulness in fulfilling his promises is a proof that he will as faithfully accomplish his threatenings, for the veracity of God is equally pledged for both.
