'Continually' in the Bible

In the presence of the ark of the LORD, he appointed some of the descendants of Levi to minister continually by remembering, giving thanks, and praising the LORD God of Israel.

The priests Benaiah and Jahaziel played the trumpets continually in the presence of the Ark of the Covenant of God.

Later David left the presence of the Ark of the Covenant of the LORD so Asaph and his fellow descendants of Levi could serve the ark there continually each day, doing whatever was required.
