'Task' in the Bible

They ministered with song in front of the tabernacle, the tent of meeting, until Solomon built the Lord’s temple in Jerusalem, and they performed their task according to the regulations given to them.

Then on that day David first entrusted to Asaph and his relatives to give thanks to the Lord [as their chief task].

Then King David said to all the assembly, “My son Solomon—God has chosen him alone—is young and inexperienced. The task is great because the temple will not be for man but for the Lord God.
