  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  Astronomy 
  The  Hebrews  were  devout  students  of  the  wonders  of  the  starry 
  firmanent  (Amos  5:8;  Ps  19).  In  the  Book  of  Job,  which  is  the 
  oldest  book  of  the  Bible  in  all  probability,  the  constellations 
  are  distinguished  and  named  Mention  is  made  of  the  "morning 
  star"  (Rev.  2:28;  comp.  Isa.  14:12),  the  "seven  stars"  and 
  "Pleiades,"  "Orion,"  "Arcturus,"  the  "Great  Bear"  (Amos  5:8;  Job 
  9:9;  38:31),  "the  crooked  serpent,"  Draco  (Job  26:13),  the 
  Dioscuri  or  Gemini,  "Castor  and  Pollux"  (Acts  28:11).  The  stars 
  were  called  "the  host  of  heaven"  (Isa.  40:26;  Jer.  33:22). 
 
  The  oldest  divisions  of  time  were  mainly  based  on  the 
  observation  of  the  movements  of  the  heavenly  bodies,  the 
  "ordinances  of  heaven"  (Gen.  1:14-18;  Job  38:33;  Jer.  31:35; 
  33:25).  Such  observations  led  to  the  division  of  the  year  into 
  months  and  the  mapping  out  of  the  appearances  of  the  stars  into 
  twelve  portions,  which  received  from  the  Greeks  the  name  of  the 
  "zodiac."  The  word  Mazzaroth"  (Job  38:32)  means  as  the  margin 
  notes,  "the  twelve  signs"  of  the  zodiac.  Astronomical 
  observations  were  also  necessary  among  the  Jews  in  order  to  the 
  fixing  of  the  proper  time  for  sacred  ceremonies,  the  "new 
  moons,"  the  "passover,"  etc  Many  allusions  are  found  to  the 
  display  of  God's  wisdom  and  power  as  seen  in  the  starry  heavens 
  (Ps.  8;  19:1-6;  Isa.  51:6,  etc.)
