Jamieson, Fausset y Brown sobre Salmos 50

PSALM 50 Psa 50:1-23. In the grandeur and solemnity of a divine judgment, God is introduced as instructing men in the nature of true worship, exposing hypocrisy, warning the wicked, and encouraging the pious. 1-4. The description of this majestic appearance of God resembles that of His giving the law (compare Ex 19:16; 20:18; De 32:1).

5. my saints--(Psa 4:3). made--literally, "cut" a covenant, &c.--alluding to the dividing of a victim of sacrifice, by which covenants were ratified, the parties passing between the divided portions (compare Ge 15:10, 18).

6. The inhabitants of heaven, who well know God's character, attest His righteousness as a judge.

7. I will testify--that is, for failure to worship aught. thy God--and so, by covenant as well as creation, entitled to a pure worship.

8-15. However scrupulous in external worship, it was offered as if they conferred an obligation in giving God His own, and with a degrading view of Him as needing it [Psa 50:9-13]. Reproving them for such foolish and blasphemous notions, He teaches them to offer, or literally, "sacrifice," thanksgiving, and pay, or perform, their vows--that is, to bring, with the external symbolical service, the homage of the heart, and faith, penitence, and love. To this is added an invitation to seek, and a promise to afford, all needed help in trouble.

16-20. the wicked--that is, the formalists, as now exposed, and who lead vicious lives (compare Ro 2:21, 23). They are unworthy to use even the words of God's law. Their hypocrisy and vice are exposed by illustrations from sins against the seventh, eighth, and ninth commandments.

21-22. God, no longer (even in appearance) disregarding such, exposes their sins and threatens a terrible punishment.

23. offereth praise--(Psa 50:14), so that the external worship is a true index of the heart. ordereth ... aright--acts in a straight, right manner, opposed to turning aside (Psa 25:5). In such, pure worship and a pure life evince their true piety, and they will enjoy God's presence and favor.
