For Jehovah is our judge. The Prophet now explains the manner in which God dwells in the Church. It is, that he is there worshipped and acknowledged as Judge, Lawgiver, and King; for they who obey God and yield subjection to him as their King, shall know by experience that he is the guardian of their salvation; but they who falsely glory in his name, vainly hope that he will assist them. Let us only yield to his authority, hear his voice, and obey him; and, on the other hand, he will shew that he is our protector and most faithful guardian. But when we despise his voice and disobey his word, we undoubtedly have no reason to wonder that he abandons and forsakes us in dangers. Hence, also, we ought to observe what is the true Church of God. It is that which acknowledges God to be a "Lawgiver" and "King." With what effrontery, therefore, do the Papists dare to boast that they are the Church of God, seeing that they reject that lawful government of it which was enjoined by Moses, and the Prophets, and Christ, and substitute in the room of it inventions and base traffic? They exert a cruel tyranny over consciences, and, by taking away all the liberty which Christ has bestowed on us, they wretchedly harass souls and lead them to perdition; but God alone has the right to rule the conscience, because he alone is "Lawgiver" and "Judge," and he alone ought to rule and guide us by his word. He combines here the three words, "Judge," "Lawgiver" and King," because the subject is of very great importance, and ought not to be lightly set aside. If, therefore, we permit ourselves to be guided by his word, he will never fail us; and this is the only way of obtaining salvation.

For the Lord is our judge - Yahweh will be to us nothing but a source of happiness, truth, and prosperity. His presence will be to us only a blessing, and a means of success and joy. The repetition of the name Yahweh three times is common in the Scriptures.

For the Lord is our Judge,.... The Lord Christ, who has all judgment committed to him by the Father, who will judge his people, right their wrongs, and avenge their injuries:
the Lord is our Lawgiver; who has enacted wholesome laws for his church, writes them on their hearts, and puts his Spirit within them, to enable them to keep them:
the Lord is our King: King of saints, King of Zion, made so by his Father, owned by his church, under whose government it is in safety:
he will save us; from all sin, and from all enemies, with an everlasting salvation. The church here speaks with great pleasure of her interest in Christ under every character, and of her safety as depending upon him. The Targum is,
"the Lord is our Judge, who brought us by his power out of Egypt; the Lord is our teacher, who gave us the doctrine of the law from Sinai; the Lord is our King, he will redeem us, and take vengeance of judgment for us on the army of Gog;''
which shows that the ancient Jews understood this prophecy as referring to times yet to come.

Lord--thrice repeated, as often: the Trinity (Numbers 6:24-26).
judge . . . lawgiver . . . king--perfect ideal of the theocracy, to be realized under Messiah alone; the judicial, legislative, and administrative functions as king to be exercised by Him in person (Isaiah 11:4; Isaiah 32:1; James 4:12).

Is judge - To plead our cause against our enemies. Lawgiver - Our chief governor, to whom it belongs, to give laws, and to defend his people.
