Look up "object pattern" and, if necessary, "text object" in the
documentation. You get something like this:-

global_settings {assumed_gamma 1.0}

camera {location  <1,1,-3> look_at <1,0,0>}

light_source {<0,3,-5> color rgb 1}

#declare T= text {ttf "ariblk.ttf", "TEXT", 20, 0}



#declare TXTURE = texture {
   object {T
     texture {pigment {rgb 1}},
     texture {pigment {wood scale 0.1 turbulence 0.2} normal{granite}}
   }
}

sphere {<0,0,1>,1 texture {TXTURE}}
sphere {<1,1,1>,0.6 texture {TXTURE}}
sphere {<2,0.2,1>,0.4 texture {TXTURE}}
sphere {<2.6,0.4,1>,0.3 texture {TXTURE}}


// Adding the following line helps you position the text
// which might be quite difficult if it happens to miss everything

//object {T pigment {rgb 0.5}}
