Psalms 95:2

Let us come before his presence - פניו panaiv , his faces, with thanksgiving, בתודה bethodah , with confession, or with the confession-offering. Praise him for what he has all ready done, and confess your unworthiness of any of his blessings. The confession-offering, the great atoning sacrifice, can alone render your acknowledgment of sin and thanksgiving acceptable to a holy and just God.
