Charles H. Spurgeon on Psalms 91:1

Whole Psalm. The Talmud writers ascribe not only the ninety-first Psalm, but the nine ensuing, to the pen of Moses; but from a rule which will in no respect hold, that all the psalms which are without the name of an author in their respective titles are the production of the poet whose name is given in the nearest preceding title. And though it is impossible to prove that this highly beautiful ode was not written by David, the general drift of its scenery and allusions rather concur in showing that, like the last, we are indebted for it to the muse of Moses: that it was composed by him during the journey through the wilderness, shortly after the plague of the fiery serpents; when the children of Israel, having returned to a better spirit, were again received into the favour of JEHOVAH. Besides political enemies, the children of Israel in the wilderness had other evils in great numbers to encounter, from the nature and diseases of the climate, which exposed them to coups de soleil, or sun smiting, during the heat of the day; and to pestilential vapours, moon smiting, during the damp of the night, so as to render the miraculous canopy of the cloud that hung over them in the former season, and the miraculous column of fire that cheered and purified them in the latter, equally needful and refreshing. In Egypt, they had seen so much of the plague, and they had been so fearfully threatened with it as a punishment for disobedience, that they could not but be in dread of its reappearance, from the incessant fatigues of their journeying. In addition to all which, they had to be perpetually on their guard against the insidious attacks of the savage monsters and reptiles of "that great and terrible wilderness", as Moses describes it on another occasion, "wherein were fiery serpents, and scorpions, and drought; where there was no water" (De 8:15); and where, also, as we learn from other parts of Scripture, bears, lions, leopards or tigers, and "the wolf of the evening", as Jeremiah has beautifully expressed it, prowled without restraint. Now in the Psalm before us, and especially in Ps 91:6-13, we have so clear and graphic a description of the whole of these evils presented to us, as to bring its composition directly home to the circumstances and the period here pitched upon, and to render it at least needless to hunt out for any other occasion.

Whole Psalm. It is one of the most excellent works of this kind which has ever appeared. It is impossible to imagine anything more solid, more beautiful, more profound, or more ornamented. Could the Latin or any modern language express thoroughly all the beauties and elegancies as well of the words as of the sentences, it would not be difficult to persuade the reader that we have no poem, either in Greek or Latin, comparable to this Hebrew ode. Simon de Muis.

Whole Psalm. Psalm 90 spoke of man withering away beneath God's anger against sin. Psalm 91 tells of a Man, who is able to tread the lion and adder under His feet. —Undoubtedly the Tempter was right in referring this Psalm to "the Son of God" (Mt 4:6). The imagery of the Psalm seems to be in part drawn from that Passover Night, when the Destroying Angel passed through Egypt, while the faithful and obedient Israelites were sheltered by God. William Kay.

He, no matter who he may be, rich or poor, learned or unlearned, patrician or plebeian, young or old, for "God is no respecter of persons", but "he is rich to all that call upon him." Bellarmine.
