"Why do you not pardon my offenses and forgive my sins? For I will soon lie down in the dust; you will search for me, but I will be no more."
NIV
And why do You not pardon my transgression and take away my iniquity? For now shall I lie down in the dust; and [even if] You will seek me diligently, [it will be too late, for] I shall not be.
AMP
And why dost thou not pardon my transgression, and take away my iniquity? for now shall I sleep in the dust; and thou shalt seek me in the morning, but I shall not be.
KJV
