New Defender's Study Bible Notes
2:3 will not tarry. The fulfillment of God’s promises (or warnings) may seem to tarry by our reckoning. But God has an “appointed time” for their accomplishment, and we can be sure it will come on time, for He does not lie! In the New Testament, this truth which Habakkuk applied to the coming Chaldean invasion is quoted in reference to the promised return of Christ (see Hebrews 10:36-37). To us who long for His return, it may seem that He is “tarrying.” But we need rather to be patient, to “occupy” until He comes (Luke 19:13), and be ready.
