'Service' in the Bible

And it will be in the day when the Lord gives you rest from your pain and turmoil and from the harsh service in which you have been enslaved,

“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.”

“Who has stirred up and put into action one from the east [the king of Persia, Cyrus the Great]Whom He calls in righteousness to His service and whom victory meets at every step?The Lord turns nations over to himAnd subdues kings.He makes them like dust with his sword,Like wind-driven chaff with his bow.

“I have not spoken in secret,In a corner of a land of darkness;I did not say to the descendants of Jacob,‘Seek Me in vain [with no benefit for yourselves].’I, the Lord, speak righteousness [the truth—trustworthy, a straightforward correlation between deeds and words],Declaring things that are upright.
