Bring upon you all evil things According to what Moses had predicted at large, Leviticus 26. and Deuteronomy 28. For God's faithfulness is no less visible in fulfilling his threatenings than his promises. Indeed the accomplishment of his promises is a pledge that he will also fulfil his threatenings, both of them standing on the same ground, the truth of God.
