Hide Multiple Rows Based upon a variable

so why does this fail:

Private Sub HideRowsWithinProgramming_DesignPhase()
    Dim xyz_rows As Range

    
    Set xyz_rows = Sheet5.Range("C:C").Find("exmaple", , xlValues, xlWhole, xlByRows, , True).Resize(3, 1)

    
    If something here Then   'You can ignore the specifics of this IF statement as this isnt the problem.
        xyz_rows.EntireRow.Hidden = True
    Else
        xyz_rows.EntireRow.Hidden = False
    End If
End Sub
