Hebrews 12:18-24 (NIV)
You have not come to a mountain that can be touched and that is burning with fire; to darkness, gloom and storm; to a trumpet blast or to such a voice speaking words that those who heard it begged that no further word be spoken to them, because they could not bear what was commanded: “If even an animal touches the mountain, it must be stoned.” The sight was so terrifying that Moses said, “I am trembling with fear.” But you have come to Mount Zion, to the heavenly Jerusalem, the city of the living God. You have come to thousands upon thousands of angels in joyful assembly, to the church of the firstborn, whose names are written in heaven. You have come to God, the judge of all men, to the spirits of righteous men made perfect, to Jesus the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
Genesis 4:8-16 (NIV)
Now Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him. Then the LORD said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?” The LORD said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand. When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.” Cain said to the LORD, “My punishment is more than I can bear. Today you are driving me from the land, and I will be hidden from your presence; I will be a restless wanderer on the earth, and whoever finds me will kill me.” But the LORD said to him, “Not so; if anyone kills Cain, he will suffer vengeance seven times over.” Then the LORD put a mark on Cain so that no one who found him would kill him. So Cain went out from the LORD’s presence and lived in the land of Nod, east of Eden.
Deuteronomy 28:65-67 (NIV)
Among those nations you will find no repose, no resting place for the sole of your foot. There the LORD will give you an anxious mind, eyes weary with longing, and a despairing heart. You will live in constant suspense, filled with dread both night and day, never sure of your life. In the morning you will say, “If only it were evening!” and in the evening, “If only it were morning!”–because of the terror that will fill your hearts and the sights that your eyes will see.
