'Mission' in the Bible

So the men told her, "Our life for yours even to death if you don't betray this mission of ours. Then when the LORD gives us this land, we'll treat you graciously and faithfully."

The priest responded to them, "Travel in peace. The mission that you're to accomplish is from the LORD."

The LORD sent you on a mission: "Go and completely destroy the sinners, the Amalekites, and fight against them until they're destroyed.'

Saul told Samuel, "I did obey the LORD. I went on the mission on which the LORD sent me, I brought Agag king of Amalek, and I completely destroyed the Amalekites.

David answered the priest, saying to him, "Indeed, women were kept from us as is usual whenever I go out on a mission, and the equipment of the young men is consecrated even when it's an ordinary journey, so how much more is their equipment consecrated today?"

David told Ahimelech, "Is there no spear or sword available here? I took neither my sword nor my weapons with me, because the king's mission is urgent."

Later, Haggith's son Adonijah approached Solomon's mother. "Are you here on a peaceful mission?" she asked.

When Barnabas and Saul had fulfilled their mission, they returned from Jerusalem, bringing with them John who was also called Mark.

All of them are spirits on a divine mission, sent to serve those who are about to inherit salvation, aren't they?
