Psalms 78:57

For that generation crooked and embittering, inasmuch as for these corporal blessings they put not off the coat of oldness, "Did tempt" yet, "and provoked the high God, and His testimonies they kept not: and they turned them away, and they kept not the covenant, like their fathers." For under a sort of covenant and decree they said, "All things which our Lord God hath spoken we will do, and we will hear." It is a remarkable thing indeed which he saith, "like their fathers:" while throughout the whole text of the Psalm he was seeming to speak of the same men as it were, yet now it appeareth that the words did concern those who were already in the land of promise, and that the fathers spoken of were of those who did provoke in the desert. "They were turned," he saith, "into a crooked," or, as some copies have it, "into a perverse bow." But what this is doth better appear in that which followeth, where he saith, "And unto wrath they provoked Him with their hills." It doth signify that they leaped into idolatry. The bow then was perverted, not for the name of the Lord, but against the name of the Lord: who said to the same people, "Thou shalt have none other Gods but Me." But by the bow He doth signify the mind's intention. This same idea, lastly, more clearly working out, "And in their graven idols," he saith, "they provoked Him to indignation."

But turned back,....

Idolatry was the sin that did most easily beset them, and which, though they often professed their repentance for, they as often relapsed into. It was spiritual adultery either to worship idols or to worship God by images, as if he had been an idol, and therefore by it they are said to move him to jealousy, Deut. xxxii. The judgments God brought upon them for these sins.

But turned back. Turned over the old leaf, repeated the same offences, started aside like an ill made bow, were false and faithless to their best promises. And dealt unfaithfully like their fathers, proving themselves legitimate by manifesting the treachery of their sires. They were a new generation, but not a new nation—another race yet not another. Evil propensities are transmitted; the birth follows the progenitor; the wild ass breeds wild asses; the children of the raven fly to the carrion. Human nature does not improve, the new editions contain all the errata of the first, and sometimes fresh errors are imported. They were turned aside like a deceitful bow, which not only fails to send the arrow towards the mark in a direct line, but springs back to the archer's hurt, and perhaps sends the shaft among his friends to their serious jeopardy. Israel boasted of the bow as the national weapon, they sang the song of the bow, and hence a deceitful bow is made to be the type and symbol of their own unsteadfastness; God can make men's glory the very ensign of their shame, he draws a bar sinister across the escutcheon of traitors.
