The relationship between worship and monarchy is analyzed in the light of Psalm 101, being emphasized the vv. 2 and 6, where above all, they are noticed indications to allow to explore this relationship. In the poem the king wants to sing the love and the right of YHWH, divine gifts granted to Israel and David, not only responding through the cult, but also through a faithful lifestyle according to the Law of YHWH. This life project, road without stain, becomes the criterion in the choice of his collaborators, and should rule the lives of all inhabitants of the city of God. Through the question when will you come to me? in v. 2, the king claims the arrival of YHWH to him, so that he might be capable to accomplish his fidelity purposes. In v. 6 the verb to serve, is used to designate the cultic service to God, and here it designates the service to the king, it seems to indicate the proximity between the monarchic atmosphere and the cultic atmosphere. This proximity also infers the royal speech, which reveals that the criterion that orientates the king s life and of those who are admitted to the court, is similar to what, according to the entrance liturgies, should guide the life of those who are admitted to the temple: the fidelity to the Law. Thus, in v. 2 the king recognizes his dependence on YHWH and, in v.6, the king establishes his court, in a certain way, in dependence on the temple.
