Adam Clarke on Habakkuk 1:12

Art thou not frown everlasting - The idols change, and their worshippers change and fail: but thou, Jehovah, art eternal; thou canst not change, and they who trust in thee are safe. Thou art infinite in thy mercy; therefore, "we shall not die," shall not be totally exterminated.

Thou hast ordained them for judgment - Thou hast raised up the Chaldeans to correct and punish us; but thou hast not given them a commission to destroy us totally.

Instead of לא נמות lo namuth, "we shall not die," Houbigant and other critics, with a little transposition of letters, read אל אמת El emeth, "God of truth;" and then the verse will stand thus: "Art thou not from everlasting, O Jehovah, my God, my Holy One? O Jehovah, God of Truth, thou hast appointed them for judgment." But this emendation, however elegant, is not supported by any MS.; nor, indeed, by any of the ancient versions, though the Chaldee has something like it. The common reading makes a very good sense.
