There's an absolution in Matins & an absolution in the Liturgy of the Word asking God to forgive us our sins. They aren't replacements for confession, you still have to confess your sins to be forgiven, and if someone comes after the absolutions but before the Gospel they can still receive Communion having received absolution in confession. After the absolution in the Liturgy of the Word the priest circles the Church with the censor, as if collecting the people's sins. He also does this in Matins. Later the priest take puts his hands over the censor and collects the incense in his hands, and puts it on the Lamb, putting the sins of the people and the sins he's taken in confession on the Lamb.
