Isa 42: 21

(KJV)
The Lord is well pleased for his righteousness’ sake; he will magnify the law, and make it honourable.
 it: or, him
(NASB2020)
The Lord was pleased for His righteousness’ sake
To make the Law bgreat and glorious.
(NET2full)
The Lord wanted to exhibit his justice
by magnifying his law and displaying it.
tn Heb “The Lord was pleased for the sake of his righteousness [or “justice”], he was magnifying [the] law and was making [it] glorious.” The Lord contrasts his good intentions for the people with their present crisis (v. 22). To demonstrate his just character and attract the nations, the Lord wanted to showcase his law among and through Israel (Deut 4:5-8). But Israel disobeyed (v. 24) and failed to carry out their commission.
