They that come after him shall be astonied at his day, as they that went before were affrighted.
After... before - rather, 'those in the West-those in the East' - i:e., all people; literally, those behind-these before; because Orientals, in geography, turn with their face to the East (not to the North, as we do), and back to the West; so that before-East: behind-West (so Zechariah 14:8, "the former (i:e., Eastern) sea-the hinder (Western) sea"). However, the English, version is good sense: "they that went before" are the sinner's contemporaries, contrasted with "those that come after him."
Day - of ruin (Obadiah 1:12; Psalms 37:13; Psalms 137:7).
Affrighted - seized with terror (Job 21:6; Isaiah 13:8).
