2. I have heard thy speech--Thy revelation to me concerning the coming chastisement of the Jews [CALVIN], and the destruction of their oppressors. This is Habakkuk's reply to God's communication [GROTIUS]. MAURER translates, "the report of Thy coming," literally, "Thy report."
      and was afraid--reverential fear of God's judgments (Hab 3:16).
      revive thy work--Perfect the work of delivering Thy people, and do not let Thy promise lie as if it were dead, but give it new life by performing it [MENOCHIUS]. CALVIN explains "thy work" to be Israel; called "the work of My hands" (Isa 45:11). God's elect people are peculiarly His work (Isa 43:1), pre-eminently illustrating His power, wisdom, and goodness. "Though we seem, as it were, dead nationally, revive us" (Ps 85:6). However (Ps 64:9), where "the work of God" refers to His judgment on their enemies, favors the former view (Ps 90:16, 17; Isa 51:9, 10).
      in the midst of the years--namely, of calamity in which we live. Now that our calamities are at their height; during our seventy years' captivity. CALVIN more fancifully explains it, in the midst of the years of Thy people, extending from Abraham to Messiah; if they be cut off before His coming, they will be cut off as it were in the midst of their years, before attaining their maturity. So BENGEL makes the midst of the years to be the middle point of the years of the world. There is a strikingly similar phrase (Da 9:27), In the midst of the week. The parallel clause, "in wrath" (that is, in the midst of wrath), however, shows that "in the midst of the years" means "in the years of our present exile and calamity."
      make known--Made it (Thy work) known by experimental proof; show in very deed, that this is Thy work.
