If only we knew the power of your anger! Your wrath is as great as the fear that is your due.
NIV
Who knows the power of Your anger? [Who worthily connects this brevity of life with Your recognition of sin?] And Your wrath, who connects it with the reverent and worshipful fear that is due You?
AMP
Who knoweth the power of thine anger? even according to thy fear, so is thy wrath.
KJV
Yet you sweep people away in the sleep of death – they are like the new grass of the morning:
NIV
You carry away [these disobedient people, doomed to die within forty years] as with a flood; they are as a sleep [vague and forgotten as soon as they are gone]. In the morning they are like grass which grows up--
AMP
Thou carriest them away as with a flood; they are as a sleep: in the morning they are like grass which groweth up.
KJV
