The same theme is repeated in the exapostilarion, a hymn which occurs near the end of the liturgy. These liturgies follow much the same pattern as liturgies on weekdays of Great Lent. The liturgies are so laid out that the entire Psalter (with the exception of Kathisma XVII) is chanted on the first three days of Holy Week. The canon that is chanted on these days is a "Triode", i.e., composed of three odes instead of the usual nine, as is in other weekday liturgies in the Triodion.
