5:20 brightness. In addition to denoting physical light, the Hebrew word for “brightness” is associated with the Lord (Ps. 18:12; Is. 4:5) and with the righteous (Prov. 4:18, 19; Is. 60:3; 62:1). There will be no light of righteousness in the land, and no brightness from the Lord’s favorable countenance. Judgment will be black and total, engulfing the whole land.
