King James Version
For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry.English Standard Version
For still the vision awaits its appointed time; it hastens to the end--it will not lie. If it seems slow, wait for it; it will surely come; it will not delay.New International Version
For the revelation awaits an appointed time; it speaks of the end and will not prove false. Though it linger, wait for it; it will certainly come and will not delay.
