Correct Syntax For Parameters When Creating SQL Job

I'm trying to create a SQL job in SQL Server and am a little unclear about the formatting.
Here's a snippet from the stored procedure that creates the job:
CREATE PROCEDURE [dbo].[spArchive]

    @DB            varchar(30),
    @Date        DateTime
AS

EXEC msdb.dbo.sp_add_jobstep @job_name = 'ArchiveIncentives'
    , @step_id = 1
    , @step_name = 'ArchiveAHD'
    , @subsystem = 'TSQL'
    , @command = 'spArchiveAHD ''@Date'''
    , @on_success_action = 3
    , @on_fail_action = 2
    , @database_name = '@DB'
    , @retry_attempts = 1 

 
In this case, the job will be calling this stored procedure:
CREATE PROCEDURE [dbo].[spArchiveAHD]
(
    @dtArchiveBefore DateTime
)
AS
 
I'm unclear about these lines:
    @command = 'spArchiveAHD ''@Date'''
    @database_name = '@DB' 

 
Do they look correct to you or should I drop some/all of the apostrophes?
