The elite force were known as “The Immortals” because they were kept constantly at a strength of exactly 10,000 men, every killed or seriously wounded member was immediately replaced. To insure loyalty, the original members of this “immortal” fighting machine were Persians by bloodline and trained from early childhood (age 7+). Not everyone could become one of the 10,000 since the training was very rigorous and hard both physically and psychologically.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. ~Ephesians 6:12 KJV~ ✨
