“The Chaldeans.” The Hebrew text has “he,” (or “it”) referring to the Babylonians (here called Chaldeans), referring to the nation as a single “he,” which is confusing in English (see commentary on Habakkuk 1:7). The REV does not normally substitute the proper noun for the pronoun, but in this case the “he” could be so confusing in the context that we opted to put in the proper noun, as did some other versions (cp. HCSB; GWN; NASB; NET; NRSV).
