Psalm 89:10 Douay-Rheims

The days of our years in them are threescore and ten years. But if in the strong they be fourscore years: and what is more of them is labour and sorrow. For mildness is come upon us: and we shall be corrected.

“For in the most general sense it holds good that it is apparently not possible for any person to remain altogether without experience of ill. For, as one says, "the whole world lies in wickedness"; and again, "Most of the days of human life are labor and trouble." But you will perhaps say, "What difference is there between being tempted, and falling or entering into temptation?" Well, if one is overcome by evil—and he will be overcome unless he struggles against it himself and unless God protects him with his shield—that person has entered into temptation, and is in it and is brought under it like one that is led captive. But if one withstands and endures, he is indeed tempted; but he has not entered into temptation or fallen into it. Thus Jesus was led up of the Spirit, not indeed to enter into temptation but to be tempted of the devil. And Abraham, again, did not enter into temptation, neither did God lead him into temptation, but he tried [tested] him; yet he did not drive him into temptation. The Lord, moreover, tested the disciples. Thus the wicked one, when he tempts us, draws us into the temptations, as dealing himself with the temptations of evil. But God, when he tests, presents the tests as one untempted by evil. For God, it is said, "cannot be tempted by evil." The devil, therefore, drives us on by violence, drawing us to destruction; but God leads us by hand, training us for our salvation.”

“Let everyone above all have this zeal in common so that having made a beginning they not hesitate or grow fainthearted in their labors or say, "We have spent a long time in ascetic discipline." Instead, as though we were beginning anew each day, let each of us increase in fervor. For the entire lifetime of a human being is very brief when measured against the age to come; accordingly, all our time here is nothing compared with life eternal. Everything in the world is sold according to its value and things of equal value are exchanged, but the promise of eternal life is purchased for very little. For it is written, "The days of our life are seventy years or, if we are strong, perhaps eighty; more than this is pain and suffering." When we persevere in ascetic discipline for all eighty or even one hundred years, we will not reign for the equivalent of those one hundred years. Instead of a hundred years, we will reign forever and ever. And although we are contested on earth, we will not receive our inheritance here; we have promises in heaven instead. Once more: when we lay aside this perishable body we receive it back imperishable. LIFE OF ST.”

“"The days of our age are threescore years and ten; and though men be so strong that they come to fourscore years, yet is more of them but labour and sorrow" [Psalm 90:10]. These words appear to express the shortness and misery of this life: since those who have reached their seventieth year are styled old men. Up to eighty, however, they appear to have some strength; but if they live beyond this, their existence is laborious through multiplied sorrows. Yet many even below the age of seventy experience an old age the most infirm and wretched: and old men have often been found to be wonderfully vigorous even beyond eighty years. It is therefore better to search for some spiritual meaning in these numbers. For the anger of God is not greater on the sins of Adam (through whom alone "sin entered into the world, and death by sin, and so death passed upon all men"), [Romans 5:12] because they live a much shorter time than the men of old; since even the length of their days is ridiculed in the comparison of a thousand years to yesterday that is past, and to three hours: especially since at the very time when they provoked the anger of God to send the deluge in which they perished, their life was at its longest span.”

“The days of our years because of them are seventy years The days of these years of ours, because of these iniquities of ours and because of these sins of our youth, are seventy years. and if with increase And if his days are much increased, they are eighty years. but their pride is toil and pain But all the greatness and the dominion that a person enjoys in these days are only toil and pain. Why? Because it passes quickly and we fly away. During its swift passing, we fly away and die. it passes Heb. גז, an expression of passing, as (Nahum 1:12): “they have crossed (נגוזו)”; (Num. 11: 31), “and drove (ויגז) quails up from the sea.””

“The days of our years are threescore years and ten,.... In the Hebrew text it is, "the days of our years in them are", &c. (a); which refers either to the days in which we live, or to the persons of the Israelites in the wilderness, who were instances of this term of life, in whom perhaps it first took place in a general way: before the flood, men lived to a great age; some nine hundred years and upwards; after the flood, men lived not so long; the term fixed then, as some think, was an hundred and twenty years, grounding it on the passage in Gen 6:3, but now, in the time of Moses, it was brought to threescore years and ten, or eighty at most: of those that were numbered in the wilderness of Sinai, from twenty years and upwards, there were none left, save Joshua and Caleb, when the account was taken in the plains of Moab; see Num 14:29, so that some must die before they were sixty; others before seventy; and perhaps all, or however the generality of them, before eighty: and, from that time, this was the common age of men, some few excepted; to the age of seventy David lived, Sa2 5:4, and so it has been ever since; many never come up to it, and few go beyond it: this is not only pointed at in revelation, but is what the Heathens have observed. Solon used to say, the term of human life was seventy years (b); so others; and a people called Berbiccae, as Aelianus relates (c), used to kill those of them that lived above seventy years of age, having exceeded the term of life. The Syriac version is, "in our days our years are seventy years"; with which the Targum agrees, "the days of our years in this world are seventy years of the stronger;'' for it is in them that such a number of years is arrived unto; or "in them", that is, in some of them; in some of mankind, their years amount hereunto, but not in all: "and if by reason of strength they be fourscore years"; through a good temperament of body, a healthful and strong constitution, under a divine blessing, some may arrive to the age of eighty; there have been some instances of a strong constitution at this age and upwards, but not very common; see Jos 14:11, for, generally speaking, such who through strength of body live to such an age, yet is their strength labour and sorrow; they labour under great infirmities, feel much pain, and little pleasure, as Barzillai at this age intimates, Sa2 19:35, these are the evil days (d), in which is no pleasure, Ecc 12:1, or "their largeness or breadth is labour and sin" (e); the whole extent of their days, from first to last, is spent in toil and labour to live in the world; and is attended with much sin, and so with much sorrow: for it is soon cut off; either the strength of man, or his age, by one disease or incident or another, like grass that is cut down with the scythe, or a flower that is cropped by the hand; see Job 14:2, and we fly away; as a shadow does, or as a bird with wings; out of time into eternity; from the place of our habitation to the grave; from a land of light to the regions of darkness: it is well if we fly away to heaven and happiness.

“In them. Years, (Calmet) “in the world.” Chaldean, “altogether.” Symmachus, years. This was the usual term of man’s life in David’s time, (Haydock) and about the captivity, when this was written. Many lived above one hundred years when Moses wrote. (Calmet) — Yet this proves nothing, as there are still instances of equal longevity, though it is true, that people in general seldom live above seventy, or eighty, or if they do, their days are a burden to them. The same might be the case under Moses. He probably here alludes to those warriors, who were cut off in the wilderness, few of whom would survive 80. (Berthier) — The author of Ecclesiasticus, (xviii. 8.) gives one hundred, for the utmost limits of life. The pagan sages speak in the same style as the psalmist. (Calmet) — Strong. Septuagint, “in dominion.” But here it means in a vigorous constitution. (Bellarmine) — Princes lived no longer than others. Hebrew and Vulgate may be “the prime, or most of them,” as even a great part of the time before seventy, as well as after, (Haydock) is usually spent in misery, Genesis xlvii. 9. (Calmet) — Mildness. God’s mildness corrects us: in as much as he deals kindly with us, in shortening the days of this miserable life; and so weaning our affections from all its transitory enjoyments, and teaching us true wisdom. (Challoner) — Hebrew, “we pass quickly and fly away, (St. Jerome) like birds of passage, (Calmet) or “it is cut down soon,” (Montanus) “in silence,” (Drusius) tacitisque senescimus annis. (Haydock) — St. Jerome wonders, that the Septuagint should have translated as they have done: But they are followed by Theodotion, and the Sext. edition, who may have had different copies, equally good. (Berthier) — Corrected ( corripiemur ) or “hurried away,” Genebrard. — But this is not the sense of the Septuagint. (Amama) — “We grow tired.” (Houbigant) — It is a mercy of God to shorten men’s lives, (Menochius) as many would sin more, if they had a probability of continuing upon earth. (Worthington)”
