John Trapp on Isaiah 42:4

Ver. 4. He ſhall not fail, nor be diſcouraged] Non erit triſtis nec turbulentus, ſo the Vulgar hath it: he ſhall be maſter of his paſſions, and keep an even ſtate of his looks and motions, whatever befall, as they report of Socrates. He ſhall not knit his brows, or chide (which was Eli's fault, 1 Sam. 3.13. but is Chriſts commendation) ſo Lud. de Dieu rendereth it. He ſhall not make to ſmoke (ſo Junius from ver. 3.) nor ſhall he bruiſe any one.

Ʋntil he have ſet Judgement] See on ver. 3.

And the Iles ſhall wait for his Law] Heb. ſhall with deſire expect his doctrine.
