Psalmen 78:51

This psalm is historical; it is a narrative of the great mercies God had bestowed upon Israel, the great sins wherewith they had provoked him, and the many tokens of his displeasure they had been under for their sins. The psalmist began, in the foregoing psalm, to relate God's wonders of old, for his own encouragement in a difficult time; there he broke off abruptly, but here resumes the subject, for the edification of the church, and enlarges much upon it, showing not only how good God had been to them, which was an earnest of further finishing mercy, but how basely they had conducted themselves towards God, which justified him in correcting them as he did at this time, and forbade all complaints.

As to the particulars, we are here told, 1. What wonderful works God had wrought for them in bringing them out of Egypt (Psa 78:12-16), providing for them in the wilderness (Psa 78:23-29), plaguing and ruining their enemies (Psa 78:43-53), and at length putting them in possession of the land of promise (Psa 78:54, Psa 78:55). 2. How ungrateful they were to God for his favours…
