The Lord would involve Himself in Judah"s situation personally, His name being the summation of His character (cf. Exodus 3:15; Ezekiel 1:28). He would come from heaven to judge the nations. The imagery of the passage is strongly anthropomorphic and theophanic (cf. Exodus 13:21; Exodus 19:18; Psalm 18:7-15; Psalm 50:3; Nahum 1:3-8; Habakkuk 3:3-15). "Anthropomorphic" means in human form, and "theophanic" means Godlike in appearance. God"s anger burned like fire, and His judgment would overwhelm people like a flood. He would sift the nations in judgment like grain in a sieve, and He would control them as a rider directs his horse. [source][source][source]
