And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more. He shall judge among the nations - as a sovereign umpire and governor, settling all controversies (cf. Isaiah 11:4).
And shall rebuke many people - argue so as to convince (Gesenius). (Job 32:12; Hebrew, howkiyach (H3198).) Lowth translates, work conviction.
They shall beat their swords into plowshares - in the East resembling a short sword (Isaiah 9:6-7; Zechariah 9:10).
