Charles Spurgeon Commentary Habakkuk 2:3

"For the vision is yet for the appointed time, and it hasteth toward the end, and shall not lie: though it tarry, wait for it; because it will surely come, it will not delay." — Habakkuk 2:3 (ASV)

Is that a contradiction—Though it tarry, ... it will not tarry?

No; to us, it appears to tarry; but, in God's way of reckoning, it does not really tarry. To our impatient spirits, it seems long in coming; but God knows that it will not be a moment beyond the appointed time.
