Context is everything. The words "La Patria es Primero" refer to putting the country's concerns over one's own, not over those of other countries. A fitting motto for the Senate, in which legislators are supposed to put the country's concerns over their own.

The words were (allegedly) spoken by Vicente Guerrero during the Mexican independence war. As a revolutionary leader he was wanted by the Spanish viceregal government but was offered a pardon and a new job as a general in the Spanish army in exchange for stopping the insurrection. He stated (to his own father, no less) that he had always respected his father, but the homeland comes first.
