A wave offering names a specified presentation within worship instructions, while Isaiah uses related brandishing language for the Lord's hand against Egypt. Exodus describes portions presented during the ordination account and also gold brought as an offering by willing people. Leviticus names portions available to the priestly household and a provision in the cleansing rite for a person of limited means.
Numbers presents the Levites for their service in relation to the sanctuary. Isaiah's brandished hand belongs to its announcement concerning Egypt, whose unit continues to address Egypt, Assyria and Israel through the Lord's blessing. These uses do not make movement itself a spiritual technique or transfer ownership of a person to a modern leader. Teach the offering, recipient, instruction and purpose named by each unit, preserving willing participation and the actual people addressed instead of enforcing an invented gesture or demeaning women through a fear comparison.
