1These are the words of the covenant which Yahweh commanded Moses to make with the children of Israel in the land of Moab, in addition to the covenant which he made with them in Horeb. 2Moses called to all Israel, and said to them:
Your eyes have seen all that Yahweh did in the land of Egypt to Pharaoh, and to all his servants, and to all his land; 3the great trials which your eyes saw, the signs, and those great wonders. 4But Yahweh has not given you a heart to know, eyes to see, and ears to hear, to this day. 5I have led you forty years in the wilderness. Your clothes have not grown old on you, and your sandals have not grown old on your feet. 6You have not eaten bread, neither have you drunk wine or strong drink, that you may know that I am Yahweh your God. 7When you came to this place, Sihon the king of Heshbon and Og the king of Bashan came out against us to battle, and we struck them. 8We took their land, and gave it for an inheritance to the Reubenites, and to the Gadites, and to the half-tribe of the Manassites. 9Therefore keep the words of this covenant and do them, that you may prosper in all that you do. 10All of you stand today in the presence of Yahweh your God: your heads, your tribes, your elders, and your officers, even all the men of Israel, 11your little ones, your wives, and the foreigners who are in the middle of your camps, from the one who cuts your wood to the one who draws your water, 12that you may enter into the covenant of Yahweh your God, and into his oath, which Yahweh your God makes with you today, 13that he may establish you today as his people, and that he may be your God, as he spoke to you and as he swore to your fathers, to Abraham, to Isaac, and to Jacob. 14Neither do I make this covenant and this oath with you only, 15but with those who stand here with us today before Yahweh our God, and also with those who are not here with us today 16(for you know how we lived in the land of Egypt, and how we came through the middle of the nations through which you passed; 17and you have seen their abominations and their idols of wood, stone, silver, and gold, which were among them); 18lest there should be among you man, woman, family, or tribe whose heart turns away today from Yahweh our God, to go to serve the gods of those nations; lest there should be among you a root that produces bitter poison; 19and it happen, when he hears the words of this curse, that he bless himself in his heart, saying, “I shall have peace, though I walk in the stubbornness of my heart,” to destroy the moist with the dry. 20Yahweh will not pardon him, but then Yahweh’s anger and his jealousy will smoke against that man, and all the curse that is written in this book will fall on him, and Yahweh will blot out his name from under the sky. 21Yahweh will set him apart for evil out of all the tribes of Israel, according to all the curses of the covenant written in this book of the law.
22The generation to come—your children who will rise up after you, and the foreigner who will come from a far land—will say, when they see the plagues of that land, and the sicknesses with which Yahweh has made it sick, 23that all of its land is sulfur, salt, and burning, that it is not sown, doesn’t produce, nor does any grass grow in it, like the overthrow of Sodom, Gomorrah, Admah, and Zeboiim, which Yahweh overthrew in his anger, and in his wrath. 24Even all the nations will say, “Why has Yahweh done this to this land? What does the heat of this great anger mean?”
25Then men will say, “Because they abandoned the covenant of Yahweh, the God of their fathers, which he made with them when he brought them out of the land of Egypt, 26and went and served other gods and worshiped them, gods that they didn’t know and that he had not given to them. 27Therefore Yahweh’s anger burned against this land, to bring on it all the curses that are written in this book. 28Yahweh rooted them out of their land in anger, in wrath, and in great indignation, and thrust them into another land, as it is today.”
29The secret things belong to Yahweh our God; but the things that are revealed belong to us and to our children forever, that we may do all the words of this law.
We typically tend to see the word “bitterness” in this verse and think immediately and only of being unwilling to forgive. But is that really the only issue the author of Hebrews had in mind?
Hebrews 12:15 is an allusion to Deuteronomy 29:18-19 (referring back to an Old Testament passage without directly quoting it). In these verses there is a reference to a “root bearing bitter fruit” in a way that fits much better with the context of Hebrews 12 than the idea of anger or unwillingness to forgive alone.
Beware lest there be among you a root bearing poisonous and bitter fruit, one who, when he hears the words of this sworn covenant, blesses himself in his heart, saying, ‘I shall be safe, though I walk in the stubbornness of my heart.’ This will lead to the sweeping away of moist and dry alike. Deuteronomy 29:18b-19 (ESV)
In Deuteronomy 29:18, the “root of bitterness” speaks of a person who hears the Word of God but then makes a conscious choice to disobey. Not only does he choose to disobey, but he also wrongly believes he will be immune from the consequences of his sin and the discipline of God. “I shall be safe, though I walk in the stubbornness of my heart.” The fruit produced by this bitter root is poison to the community of God’s people.
The primary focus of Hebrews 12 is the fatherly love with which God consistently disciplines those who are his children. His discipline is shown to be proof of his love and a painful part of building holiness in His people. This is pictured in the next verses by Esau’s choice to trade his future birthright for a measly bowl of soup. The momentary decision he made had irreversible long-term consequences, just as sexual immorality also does.
No child of God can expect to willfully disobey the Word of God without seeing firsthand the discipline of our loving Father. To suggest otherwise is a “root of bitterness” that must be dug up and cast aside. For some, that may be an unforgiving attitude, but it would not do justice to this verse to see only that attitude at stake. We must view obedience to God’s Word in every area of life as absolutely necessary.
