'Warfare' in the Bible

but at the age of fifty years, they shall retire from the service of the [tabernacle] work and serve no longer.

“Is not man forced to labor on earth?And are not his days like the days of a hired man?

“If a man dies, will he live again?I will wait all the days of my struggleUntil my change and release will come.

They [of Babylon] will be shocked and terrified,Pains and anguish will grip them;They will be in pain like a woman in childbirth.They will stare aghast and horrified at one another,Their faces aflame [from the effects of the unprecedented warfare].

“Speak tenderly to Jerusalem,And call out to her, that her time of compulsory service in warfare is finished,That her wickedness has been taken away [since her punishment is sufficient],That she has received from the Lord’s handDouble [punishment] for all her sins.”

“Therefore, behold, the days are coming,” declares the Lord, “when it will no longer be called Topheth or the Valley of Ben-hinnom, but the Valley of the Slaughter, for [in bloody warfare] they will bury [the dead] in Topheth until there is no more room.
