Judaism
Names are attributed added significance in traditional Jewish sources.

Biblical names
In the Old Testament, we find that names of individuals are meaningful. Adam is named after the "earth" (Adama) from which he was created. (Genesis 2)
A change of name indicates a change of status. For example, the patriarch "Abram" is renamed "Abraham" before he is blessed with children. His wife, "Sarai" is similarly renamed "Sarah." (Genesis 17)

Talmudic attitudes
The Babylonian Talmud maintains that names exert an influence over their bearers:
From where do we know that a name has a causal effect ("shama garim"). Says Rabbi Elazar: the verse says, (Psalms 46:9) "Go see the works of God, who puts desolation (shamot) in the earth." Read not "desolation" but "names" (shemot).
