John Trapp on Isaiah 51:4-5

Ver. 4. Harken unto me] See on ver. 2.

For a Law ſhall proceed from me] i. e. The Goſpel of grace, that perfect Law of liberty, the Law of the Spirit of life, Rom. 8.2.

Diod. And I will make my Judgement to reſt] I will firmly and irrevocably eſtabliſh the government of my Word and Spirit in the Church for a ſecure guide to bring it to eternal life. Some render it thus, My Judgement. (i. e. My Goſpel) ſhall be for a light of the people, whereby I will give reſt: So that here is a double effect of the Goſpel, viz Saving light, and Peace of Conſcience.

Jam amodò iter ingreſſa eſt. Hyper. Ver. 5. My righteouſneſſe] i. e. my faithfulneſſe, or my Son, that Sun of righteouſneſſe, is already on the way, and will be with you forthwith.

And mine arm ſhall judge the people] i. e. All that ſet themſelves againſt the Lord and againſt his Chriſt, Pſal. 2.2. theſe ſhall feel his power to their perdition, even the force of both his arms.

The Iles ſhall wait upon me] They ſhall ſtretch out their ſouls as a line, (ſo the word importeth) and direct them toward Chriſt.

And on mine arm ſhall they truſt] i. e. On my power, or on my Goſpel-promiſes.
