The NAB renders Habakkuk 2:3 …
"For the vision still has its time, presses on to fulfillment, and will not disappoint; If it delays, wait for it, it will surely come, it will not be late. "
The introduction to the NAB Book of Habakkuk is as follows:
This prophecy dates from the years 605-597 B.C., or between the great Babylonian victory at Carchemish and Nebuchadnezzar’s invasion of Judah which culminated in the capture of Jerusalem. The situation of Judah was desperate at this time, with political intrigue and idolatry widespread in the small kingdom. The first two chapters consist of a dialogue between the prophet and the Lord. For what may be the first time in Israelite literature, a man questions the ways of God, as Habakkuk calls him to account for his government of the world. To this question God replies that he has prepared a chastising rod, Babylon, which will be the avenging instrument in his hand. There is added the divine assurance that the just Israelite will not perish in the calamities about to be visited on the nation.
yet another translation renders it:
“For the vision is yet fore the appointed end, and strives after the end, and does not lie: if it tarry, wait for it; for it will come, it does not fail.”
The Douay Rheims Bible renders Habacuc 2:3 …
“For as yet the vision is far off, and it shall appear at the end, and shall not lie: if it make any delay, wait for it: for it shall surely come, and it shall not be slack.”
In the DRV quoted immediately above, the text for the book of Habacuc; Chapter 2, is preceded by the subheading:
The prophet is admonished to wait with faith. The enemies of God’s people shall assuredly be punished.
