"Nuestro juramento" (English: "Our oath") is a bolero by Puerto Rican songwriter Benito de Jesús and popularized throughout Latin America by Ecuadorian singer Julio Jaramillo.
[2] Jaramillo's original recording of the song was made in 1956, featuring Rosalino Quintero on requinto guitar, and released in 1957 by Ónix.
[1] The lyrics of the song talk about two lovers who have made an oath to love each other until death and beyond; if the man dies first, the woman promises to spill all her tears over his corpse and to make everyone know about her love, and if she dies first, the man promises to write the story of their love with blood from his heart.
[3] Nuestro juramento is the most popular song in the history of Ecuador, especially in Guayaquil, where Julio Jaramillo was from.
Benito de Jesús said to be living off the royalties of "Nuestro juramento".
