IV. Here is a pleasant commendation of the integrity of the two tribes, which they held fast, and this comes in as an aggravation of the perfidiousness of the ten tribes, and a reason why God had that mercy in store for Judah which he had not for Israel (ch. i. 6, 7), for Judah yet rules with God and is faithful with the saints, or with the Most Holy. 1. Judah rules with God, that is, he serves God, and the service of God is not only true liberty and freedom, but it is dignity and dominion. Judah rules, that is, the princes and governors of Judah rule with God; they use their power for him, for his honour, and the support of his interest. Those rule with God that rule in the fear of God (2 Sam. xxiii. 3), and it is their honour to do so, and their praise shall be of God, as Judah's here is. Judah is Israel—a prince with God. 2. He is faithful with the holy God, keeps close to his worship and to his saints, with Abraham, Isaac, and Jacob, whose steps they faithfully tread in. They walk in the way of good men; and those that do so rule with God, they have a mighty interest in Heaven. Judah yet does thus, which intimates that the time would come when Judah also would revolt and degenerate. Note, When we see how many there are that compass God about with lies and deceit it may be a comfort to us to think that God has his remnant that cleave to him with purpose of heart, and are faithful to his saints; and for those who are thus faithful unto death is reserved a crown of life, when hypocrites and all liars shall have their portion without.
