His soul shall dwell at ease; and his seed shall inherit the earth.
Shall dwell at ease ( luwn (H3885)) - literally, 'shall pass the night in good;' i:e., shall abide permanently in good (Job 17:2, English version, cf. margin; Proverbs 19:23). I prefer restricting the term to his passing the night of this present life (Romans 13:12) - the times of darkness and the dying hour-in peace (Psalms 23:4).
His seed shall inherit the earth - as was promised to Abraham (Genesis 12:1-20; Genesis 15:1-21); and subsequently to Israel, and to all the godly, in the New Testament, in the fullest sense (Matthew 5:5). The ungodly, with all their seed, shall be uprooted out of the earth.
