Your name, O Lord, endures throughout all ages

In Psalm 135:13, the psalmist praises God and provides these reassuring words:

Psalm 135:13 English Standard Version (ESV)

Your name, O Lord, endures forever,
your renown,[a] O Lord, throughout all ages.

In this passage, a parallel chiastic structure is used which is an element of Hebrew poetry.  The two lines of the poem accentuate the concept by stating the same idea in two ways.

Translated from literal Hebrew at studylight.org, the passage reads as follows:

Yahweh Your name [endures] forever
Yahweh Your memorial throughout generation and generation

God's name is parallel to God's renown (or remembrance): this is a reference to God's fame and glory.

The phrase endures forever is parallel to throughout all ages: this parallels the ages of this world's existence to the longest timeframe that the Hebrew language can communicate.

The literal meaning of throughout all ages is generation and generation.
And the Hebrew word translated as forever is olam meaning includes variations on the theme of long duration such as antiquity, everlasting, unending, and forever.

Therefore, God's fame and glory lasts throughout all generations which equates to the longest imaginable timeframe which is captured by the Hebrew word olam.

Genesis 2:4 contains the colophon statement for Genesis 1: "These [are] the generations of the heavens and of the earth when they were created in the day that Yahweh God made the earth and the heavens."

Ages of Joy interprets these generations in the same manner that the ESV renders Psalm 135:13, that is, as "ages".  In other words, the "generations" or "ages" of Genesis 1, plus all the ages that followed up to the time when the Psalmist wrote his words, plus the rest of the ages yet to come, span a timeframe corresponding to forever, meaning the longest imaginable and communicable timeframe available to the Hebrew language.  The everlasting nature of God is attested to by His creation.  He is eternal and His creation is from of old.

At Ages of Joy, we purport that each Day of Genesis 1 corresponds to an Age or a Generation as stated in Genesis 2:4.  Taken together, these generations contribute substantially to the overall time frame of "generation and generation", that is, the time from the beginning in Genesis 1:1 through to the next beginning in Revelation 21:1.

The ages have a "day-like" structure, with a time in which God works, and then a night/morning element that mark major transitions, like the passing of a day or the ending of an age.  Said another way, each Day is like a generation, having a beginning, but also an ending and a passing-on.

God's fame endures through the ages of creation as all the "sons of God shouted for joy" Job 38:7b.

Ages of Joy takes an expansive view of God's creative handiwork and His enduring fame and glory, first before angels and then among mankind.  Whether the ages of Genesis 1 are each thousands of years long, or million or billions of years long, cannot be discerned from the Hebrew text alone, but the implication of these passages of Scripture is that the creation week spanned a very long period of time.

Some may argue that Psalm 135 is poetry and therefore we cannot take it literally.  To this, I would respond that poetry must be interpreted and the intent of the author is to convey that God is big and His creation is old; time goes on and on, but God is always present, always renowned.  Some think of the creation week as a mere passing of several dozen hours of time, but I think we need to extend that view to think of the ages past in which God was at work and see the finiteness of man against God's eternality.

This analysis does not constitute a proof of the day-age interpretation, but does lend support to the validity of such an interpretation.
