Psalm 90 speaks of time, permanence and impermanence, and the span of human life. It upholds the eternal nature of the Lord: "Even from everlasting to everlasting, You are God."

A secondary but connected theme, especially from verses 7-12, is the Lord's apparent anger with us, and his affliction of our lives with troubles. The reason given for this is that we can then learn the true nature of our lives and of our dependence on Him.

The psalm ends with a prayer for the Lord's compassion on us, and for us to be glad all our days, according to the days of our affliction. We wish to know the work of the Lord. We hope that the work of our hands - our purpose and use - will be established.

This is a relatively profound psalm, covering many questions we have about life. It links our sense of our own frailty with the Lord's greater purposes. In the same way that 'time' is basically only an appearance to us, so our unthinking view of life is generally illusory. It can bring us to think of God as angry, and against us. But, nothing could be further from the truth. (See Heaven and Hell 165)

It's important to see that the first two verses are unambiguously true: First, "Lord, You have been our dwelling place in all generations", and second, "even from everlasting to everlasting, You are God". Spiritually, for us, holding this opening statement in our minds allows us to explore our whole relationship with the Lord. (See Arcana Caelestia 3913)

The next four verses bring out the frailty of our existence, that in a sense we are made from the dust of the earth. Spiritually, this is not said to condemn us, but to remind us that without the Lord, we are nothing. (See Arcana Caelestia 8995)

This humility allows us to come into spiritually positive territory. This is brought out in the context of time being as nothing - "a thousand years in God's sight are like yesterday" - they are carried away and temporary. (See Divine Providence 218-219)

From verse 7 onward come descriptions of the Lord's anger and wrath, along with the brevity and futility of our days in life. "We finish our years like a sigh." All of this is said in the language of appearance - of how it can seem to us - when we consider life only from our viewpoint and not from the Lord's purpose in it. (See Arcana Caelestia 1093 and Sacred Scripture 94.) In reality, the Lord does not ever have or hold anger and wrath.

Verse 12 provides a helpful clue to the verses which come before it. It is a prayer from us to the Lord to teach us to number our days, that we may gain a heart of wisdom. This is a lesson learned from our experience in life, with its pitfalls and its speedy passing, when we realise our folly too late.

The last five verses are clearer and brighter, asking the Lord to gladden us in our lives, and for us to see the work of God in all that we go through, and finally for the Lord our God to establish the work of our hands. Note that this positive ending comes from having endured confusion and negative states which we have now worked through, and that they have gone from us. (See Apocalypse Explained 897.)

6983. 'Neither since yesterday, nor since the day before' means that he has lacked it - the gift of speech - from eternity. This is clear from the meaning of 'since yesterday and since the day before' as from eternity. The reason why 'since yesterday and since the day before' means from eternity is that a period of time is meant by these words, in particular past time; but time spoken of in connection with the Lord or the Divine does not mean a period of time but what is eternal. There are two things proper to the natural order which have no existence in heaven, and even less in the Divine, namely space and time. For their non-existence in heaven and the existence of states instead - states of being instead of 'space', and states of coming-into-being or manifestation instead of 'time' - see 2625, 3938; and for the fact that areas of space and periods of time in heaven are states, 1274, 1382, 2625, 2788, 2837, 3254, 3356, 3387, 3404, 3827, 4321, 4814, 4882, 4901, 4916, 5605, 6110. But within the Divine which is above the heavens the absence of space and time is even more complete; for not even states exist within Him. Instead of space there is what is infinite, and instead of time what is eternal. These two are what periods of time or areas of space in the world correspond to, and are what states of being and of coming-into-being in the heavens correspond to.

[2] The fact that in the Word 'yesterday' and 'the day before' do not mean yesterday and the day before but past time in general is clear from places where those words are used, as in Joshua,

The waters of the Jordan returned to their place, and went as yesterday [and] the day before ¹ over all its banks. Joshua 4:18.

In the first Book of Samuel,

It happened, when all who knew Saul from yesterday and the day before ² saw that, behold, he prophesied with the prophets . . . 1 Samuel 10:11.

In the second Book of Samuel,

The tribes of Israel said to David, Both yesterday and the day before, ³ when Saul was king over us, you were the one bringing Israel out and back. 2 Samuel 5:1-2.

In these places and elsewhere 'yesterday [and] the day before' stands for previously or past time. Now since 'yesterday and the day before' means time past, and the subject in the highest sense is the Lord, who in respect of the Divine Law or Divine Truth is represented by 'Moses', it is evident that 'since yesterday and since the day before' means from eternity. Eternity, meant by 'yesterday', is described in David as follows,

A thousand years in Your eyes are but as yesterday when it is past. Psalms 90:4.
