7899. 'And you shall keep this day throughout your generations by an eternal statute' means worship that springs from faith and charity in keeping with Divine order. This is clear from the meaning of 'keeping' as worship, for that day was kept when the Passover was celebrated on it; from the meaning of 'generations' as aspects of faith and charity, dealt with above in 7883; and from the meaning of 'an eternal statute' as in keeping with Divine order, also dealt with above, in 7884.
