His heart is established
With the doctrine of grace; which is food unto it, and by which it is strengthened and nourished; it is established in the faith of Christ, both in the grace of faith, and in the doctrine of faith, even in all the doctrines of the Gospel; so that he is not as a child, tossed to and fro with every wind; his heart is established in the exercise of grace, and he is steadfast and immovable in the discharge of duty. This being the case,
he shall not be afraid, until he see his desire upon his enemies;
until he looks them in the face boldly and confidently; or until he sees them all slain and destroyed, as the Israelites saw the Egyptians on the sea shore. We supply "his desire"; it might be put "vengeance", as in ( Psalms 58:10 ) , the punishment of God on wicked men, who are the enemies of the upright; and which they shall see with pleasure, because of the glory of divine justice conspicuous therein; see ( Revelation 18:20 ) ( Revelation 19:1 Revelation 19:2 ) and even before this is brought about, while their enemies are oppressing them, insulting them, and triumphing over them, they shall not be afraid, as knowing the time is coming when the scene will be changed, and they shall triumph in their turn.
