Jl 2:12-18 is part of a thematic horizon of a penitential liturgy, where the whole community should be present and express through the liturgical rites their request for helping to YHWH. This liturgy is performed through a worship service, in the temple of Jerusalem. The priests, as leadership of the community, conduct the prayer of pleading and the community follows the ritual with prayers and gestures. This penitential liturgy has no sacrifices or material offerings, however, the own context of shortage promotes an offering of the heart, namely, a grant of the whole person. The context of Jl 2:12-18 is about a natural catastrophe which causes famine and the absence of necessary products for the livelihood. As a consequence of the crisis the people of Juda-Jerusalem also envisage a state of spiritual apathy. Nevertheless there is still hope that through a penitential liturgical service this unfavorable context can be changed. Then the prophet, following the convocation of YHWH himself, summons the community so that through a liturgical rite can accomplish the process of returning to him.
