Psalm 78:2ESV·traditional attribution

I will open my mouth in a parable; I will utter dark sayings from of old,

PSALM 78 To comprehend many things within small compass, it is to be observed, that in this psalm there are two leading topics. On the one hand, it is declared how God adopted for himself a Church from the posterity of Abraham, how tenderly and graciously he cherished it, how wonderfully he brought it out of Egypt, and how varied were the blessings which he bestowed upon it.

I will open my mouth in a parable. Analogies are not only to be imagined, but are intended by God to be traced between the story of Israel and the lives of believers. Israel was ordained to be a type; the tribes and their marchings are living allegories traced by the hand of an all wise providence.

These verses, which contain the preface to this history, show that the psalm answers the title; it is indeed Maschil - a psalm to give instruction; if we receive not the instruction it gives, it is our own fault. Here, I. The psalmist demands attention to what he wrote (Psa 78:1): Give ear, O my people! to my law. Some make these the psalmist's words.
