Leviticus 26:36

Deuteronomy 28:65-67

28:65 Among those nations you will have no rest nor will there be a place of peaceful rest for the soles of your feet, for there the Lord will give you an anxious heart, failing eyesight, and a spirit of despair. 28:66 Your life will hang in doubt before you; you will be terrified by night and day and will have no certainty of surviving from one day to the next. 28:67 In the morning you will say, ‘If only it were evening!’ And in the evening you will say, ‘I wish it were morning!’ because of the things you will fear and the things you will see.

Hebrews 10:26-27

10:26 For if we deliberately keep on sinning after receiving the knowledge of the truth, no further sacrifice for sins is left for us, 10:27 but only a certain fearful expectation of judgment and a fury of fire that will consume God’s enemies.
