John Trapp on Isaiah 42:8

Ver. 8. I am the Lord] I and no Heathen petty god, as I have plainly and plentifully proved, nemine contradicente.

That is my Name] God, though he be above all name (when Manoah enquired after his name, the anſwer was 'Tis wounderful, i. e. far above thy conception) yet here we have his proper name Jehovah; which is alſo called his glory, becauſe incommunicable to any creature.

And my glory will I not give to another] To his Son Chriſt he hath given it, Joh. 17.2. who although he is Alius, yet he is not Aliud from the Father, but of the ſame nature and eſſence. God hath given being to all things, life to many, ſenſe to others, reaſon to men and Angels, his glory he will not give to any. Excellently hereupon Bernard, My glory I will not, &c. what then wilt thou give us Lord?Ser. 13. in Cant what wilt thou give us? My peace, ſaith he, I give you, my peace I leave unto you. It's enough for me Lord; I thankfully take what thou leaveſt, and leave what thou keepeſt to thy ſelf, &c.
