'Assisted' in the Bible

He had the support of Zeruiah's son Joab and of Abiathar the priest, who followed Adonijah and assisted him,

Here's a list of those who came to David at Ziklag when he was unable to travel freely due to Saul son of Kish. They were among the elite soldiers who assisted him in battle.

Joab's brother Asahel was fourth for the fourth month, assisted by his son Zebadiah, with 24,000 soldiers in his division.

He also had various siege engines built by skilled designers and placed them on the towers and on the corner ramparts that could fire arrows and very large stones. His reputation spread far and wide, and he was marvelously assisted until he grew very strong.

Because there weren't enough priests, they were unable to prepare all the burnt offerings until other priests came forward after having consecrated themselves, so their descendant of Levi relatives assisted them until the services were complete. (The descendants of Levi had been more conscientious in consecrating themselves than had been the priests.)
