Within religious traditions, a primary aim and orientation is sometimes to secure a blessed life for descendants. In Catholic and Christian traditions, this can occur through infant baptism. In Deuteronomy 11:19 and 6:7, teaching children Torah is emphasized. And in any case, depending on social status, the performance and language which are perceived to have efficacy for blessing descendants can vary.
Naturally, Mesopotamian prayers by kings were also aimed at securing blessings for descendants. So, how did Mesopotamian’s performance rituals in order to attain and secure a blessed life for descendants? One way to think about this question is by looking at a prayer by the Assyrian king Assurbanipal .
For the majority of the prayer, Assurbanipal praises Assur . For example, the speaker exalts Assur as the creator:
[Let me exalt] the sovereignty of [Assur] forever.
[Cap]able one, profound of wisdom, sage of the gods, princely one,
[Father], creator of what is in the heavens and earth, who formed the mountains,
[Assur], creator of the gods, begetter of goddess(es),
[Whose heart] is inscrutable, whose mind is ingenious,
Lofty [hero] whose name is feared… 
Evidently, the speaker attributes creation itself to Assur, views Assur as a warrior, and consider Assur to be the wisest of all beings (i.e. “sage of the gods”).
In the second half of the hymn, we read of a focus on the descendants of Assurbanipal:
Among descendants, in far-off days,
For future reigns, years without number,
May th(is) praise of Assure be not forgotten, may it keep one mindful of Esharra, a temple in Assur.
Let it be in (every) mouth, may it never cease to enlarge understanding,
So that, as to me, Assur will deliver into your hands sovereignty of land and people .
Essentially, the speaker Assurbanipal prays for the perpetual reign of his offspring on the basis of his prayers and role in supporting the temple at Assur. Note, though, that Assurbanipal explicitly says “your hands,” with reference to his descendant. Although it is unclear whether he used a 2nd person form because his descendant is present where the hymn is performed or he imagines his descendant as being present, it is clear that the prayer is explicitly focused on his particular offspring, not the general concept of “descendants.”
Based on Assurbanipal’s father, though, this is no surprise. In a famous text typically called Esarhaddon’s Succession Treaty, a covenant stipulates that all people within the Assyrian empire ruled by Esarhaddon commit to serving his son, Assurbanipal, as king when Esarhaddon dies . Thus, the apple didn’t fall far from the tree. For just as Esarhaddon attempted to ensure that Assurbanipal maintain reign and sovereignty, so Assurbanipal attempted to ensure that his descendant maintain reign and sovereignty .
Therefore, Assurbanipal’s prayer to Assur uses religious language, imagery, and activities as a perceived means of securing political sovereignty for his offspring. This echoes how Esarhaddon ensured that Assurbanipal maintain sovereignty. At base, it demonstrates how a particular social class, namely that of the royal family, attempts to secure a blessed life for descendants.
 As noted previously, individuals and groups with different social statuses will have different rituals and performances to attain blessed life for descendants. Now, the prayer which I am analyzing here was written for Assurbanipal. So, at most the text represents the ways in which a very small and wealthy social class sought to attain blessings for descendants. Therefore, we should be careful not to apply the paradigm and rituals represented within this hymn to every social group in ancient Mesopotamia, even if they do overlap is some places.
 In particular, he praises Assur as a primeval deity called Anshar. See Benjamin Foster, Before the Muses: An Anthology of Akkadian Literature (Bethesda: CDL Press, 2005), pp. 817n1.

 Interestingly, perhaps Assurbanipal also looks backwards to his father, Esarhaddon in The Underworld Vision of an Assyrian Prince (SAA 03 032 r. 26).
