Psalms 89:30

This is a strong pledge of the promise of God. The sons of this David are the children of the Bridegroom; all Christians therefore are called His sons. But it is much indeed that God promises, that if Christians, that is, "If his children forsake My law, and walk not in My judgments" [Psalm 89:30]; "if they profane My statutes, and keep not My commandments" [Psalm 89:31]; I will not spurn them, nor will I send them away from Me in perdition: but what will I do? "I will visit their offenses with the rod, and their sin with scourges" [Psalm 89:32]. It is not the mercy of one that calls them only; but also that chastises and scourges them. Let therefore your Father's hand be upon you, and if you are a good son, repel not chastening; for "what son is there, to whom his father gives not chastening?" [Hebrews 12:7] Let Him chasten him, so long as He takes not from him His mercy: let Him beat him when obstinate, as long as He does not disinherit him. If you have well understood the promises of your Father, fear not to be scourged, but to be disinherited: "for whom the Lord loves He chastens: and scourges every son whom He receives." [Hebrews 12:6] Does the sinful son spurn chastening, when he sees the only Son without sin scourged? "I will visit their offenses with the rod." Thus too the Apostle threatens: "What will you? Shall I come unto you with a rod?" [1 Corinthians 4:21] Let not pious sons say, if You are coming with a rod, come not at all. For it is better to be taught with the Father's rod, than to perish in the caresses of the robber.

(1.) If we apply it to David, by his seed we are to understand his successors, Solomon and the following kings of Judah, who descended from the loins of David. It is supposed that they might degenerate, and not walk in the spirit and steps of their father David; in such a case they must expect to come under divine rebukes, such as the house of David was at this time under,

If his children forsake my law,....

Then--when the covenant was established, of whose execution the exalted views of God now given furnish assurance. thou . . . to thy holy one--or godly saint, object of favor (Ps 4:3). Nathan is meant (2Sa 7:17; 1Ch 17:3-15). laid help--literally, "given help." David was chosen and then exalted.

This relation is perpetual with David's descendants, as a whole typical in official position of his last greatest descendant. Hence though in personal relations any of them might be faithless and so punished, their typical relation shall continue. His oath confirms His promise, and the most enduring objects of earth and heaven illustrate its perpetual force (Ps 72:5, 7, 17).
