'Assist' in the Bible

When the Arameans of Damascus came to assist King Hadadezer of Zobah, David struck down 22,000 Aramean men.

David also issued these orders to all of the leaders of Israel to assist his son Solomon:

“but their duty will be to assist the sons of Aaron with the service of the Lord’s temple, being responsible for the courts and the chambers, the purification of all the holy things, and the work of the service of God’s temple—

"Instead, they are to assist by lending a hand to the descendants of Aaron regarding service to the Temple of the LORD relating to the courts, the chambers, purification of everything pertaining to holiness, and to anything else pertaining to service on behalf of the Temple of God, including assisting with the rows of showbread, selecting flour for the grain offerings, the unleavened bread, baked offerings, and oil-based offerings, no matter what the quantity or sizes.

and to offer all burnt sacrifices to the Lord on the Sabbaths, the new moons, and the festivals by number according to the ordinance concerning them, continually before the Lord.

Along with officers in his army, David consecrated to assist in service to the descendants of Asaph, Heman, and Jeduthun those who prophesy with lyres, harps, and cymbals.

Here are the divisions of the priests and Levites who will perform all the service of God's temple. All the willing and skilled men are ready to assist you in all the work and perform their service. The officials and all the people are ready to follow your instructions."
