A more thorough explanation:

Definition: A verger is a person who carries a rod called a verge as a symbol of their position. They are often an assistant to a bishop or a justice.

At the church, the verger led the procession carrying the Bible.

The verger escorted the bishop to his seat during the ceremony.

These examples show how a verger is a person who carries a rod and assists a bishop or justice. In the first example, the verger is leading a procession, which is a common duty for a verger in a church. In the second example, the verger is escorting the bishop, which is another common duty for a verger in a religious setting.
