Psalms 81:10

10. I am Jehovah thy God, who brought thee out of the land of Egypt: open thy mouth wide. God, by making mention of the deliverance which he had wrought for the people, put a bridle upon those whom he had taken under his protection, by which he might hold them bound to his service; and now he assures them, that with respect to the time to come, he had an abundant supply of all blessings with which to fill and satisfy their desires. The three arguments which he employs to induce the Israelites to adhere exclusively to him, and by which he shows them how wickedly and impiously they would act in turning aside from him, and having recourse to strange gods, are worthy of special attention. The first is, that he is Jehovah. By the word Jehovah, he asserts his claims as God by nature, and declares, that it is beyond the power of man to make new gods. When he says I am Jehovah, the pronoun I is emphatic. The Egyptians, no doubt, pretended to worship the Creator of heaven and of earth; but their contempt of the God of Israel plainly convicted them of falsehood. Whenever men depart from Him, they adorn the idols of their own invention with His spoils, whatever the specious pretexts may be by which they attempt to vindicate themselves. After having affirmed that he is Jehovah, he proves his Godhead from the effect and experience, — from the clear and irrefragable evidence of it in his delivering his people from Egypt, and especially, from his performing at that time the promise which he had made to the fathers. This is his second argument. The power which was displayed on that occasion ought not to have been contemplated apart by itself, since it depended upon the covenant, which long before he had entered into with Abraham. By that deliverance he gave a proof not less of his veracity than of his power, and thus vindicated the praise which was due to him. The third argument is, that he offers himself to the people for the time to come; assuring them, that, provided they continue to persevere in the faith, he will be the same towards the children as the fathers experienced him to be, his goodness being inexhaustible: Open thy mouth wide, and I will fill it. By the expression open wide, he tacitly condemns the contracted views and desires which obstruct the exercise of his beneficence. “If the people are in penury,” we may suppose him to say, “the blame is to be entirely ascribed to themselves, because their capacity is not large enough to receive the blessings of which they stand in need; or rather, because by their unbelief they reject the blessings which would flow spontaneously upon them.” He not only bids them open their mouth, but he magnifies the abundance of his grace still more highly, by intimating, that however enlarged our desires may be, there will be nothing wanting which is necessary to afford us full satisfaction. Whence it follows, that the reason why God’s blessings drop upon us in a sparing and slender manner is, because our mouth is too narrow; and the reason why others are empty and famished is, because they keep their mouth completely shut. The majority of mankind, either from disgust, or pride, or madness, refuse all the blessings which are offered them from heaven. Others, although they do not altogether reject them, yet with difficulty take in only a few small drops, because their faith is so straitened as to prevent them from receiving an abundant supply. It is a very manifest proof of the depravity of mankind, when they have no desire to know God, in order that they may embrace him, and when they are equally disinclined to rest satisfied with him. He undoubtedly here requires to be worshipped by external service; but he sets no value upon the bare name of Deity — for his majesty does not consist in two or three syllables. He rather looks to what the name imports, and is solicitous that our hope may not be withdrawn from him to other objects, or that the praise of righteousness, salvation, and all blessings, may not be transferred from him to another. In calling himself by the name Jehovah, he claims Godhead exclusively to himself, on the ground that he possesses a plenitude of all blessings with which to satisfy and fill us.
