JMNT(i)
18 "Look, and consider! My Boy (or: My Servant; My personal attendant; My servant-boy) Whom I select (or: chose) – My Beloved, [of] Whom My soul assumes ease and wellness (or: [in] Whom My soul takes pleasure; Whom My soul considers good and thinks well of)! I will proceed putting (placing) My Spirit (the effect of My breath; My Attitude) upon Him, and He will continue sending-off a message regarding separation and a decision for the ethnic multitudes (or: will repeatedly announce a judging and bring a report of justice in the nations; will continue plainly declaring what justice and discrimination is to non-Jews; will continuously announce judgment for the Gentiles [= foreigners]).
19 He will neither proceed to quarrel (strive; debate; be contentious) nor will He continue shouting (screaming or making outcry; causing clamoring; behaving loud-mouthed), nor yet will anyone continue hearing His voice [above the ambient noises] in the town squares or broad streets.
20 He will not proceed to break down a reed that has been bruised (or: break in pieces a reed that has been crushed), and He will not proceed to extinguish a flax lamp-wick that is continuing in being wrapped in smoke and made to smolder – until He can thrust-forth [the] separation-derived decision into a victory (or: cast-out judging – unto victory)!
21 And then, the ethnic multitudes (nations; pagans; foreigners; Gentiles) will proceed to be continuously placing [their] expectations in His Name (= on His character, reputation and authority)!" [Isa. 42:1-4; comment: this passage describes a Person who is gentle and non-violent in character]
