Rashi, on Isa 42:4

“He shall not be sad, nor troublesome, till he set judgment in the earth: and the islands shall wait for his law.”

“Neither shall he weaken nor shall he be broken Heb. וְלֹא יָרוּץ, like לֹא יֵרָצֵץ, he shall not be broken, “for the earth shall be full of knowledge of the Lord as water covers the seabed” (supra 11:9). And they shall obey them, as the matter is stated (Zeph. 3:9): “For then I will make the nations pure of speech etc.” That is what follows: And for his instruction islands shall long. They shall all obey his instruction.”
