Handbook of ROCOR Liturgical Practice:

The Bishop’s zhezl (crosier) is appointed to be held, carried, and in some cases processed with by a server, rather than the Bishop Himself. In such cases, the server appointed for this tasks always holds the zhezl with both hands (never one), directly in front of him, and slightly elevated so that it is not actually resting on the ground (only the Bishop actually leans upon / walks with the zhezl as a staff; servers carry it).
