In the criticism of the Song of Songs there is no agreement on the structural problem of the book. Theories are divided into those advocating a fragmentary against others who see a unitary character of poems. The study attempts to revise this problems and propose that the Song of Songs is a loose collection of poems that a compiler gathered and tried to give some order, incorporating the adjuration of 2, 7; 3,5; 5,8; 8,4 as refrain with articulate function, such that the adjuration was set as milestone dividing between large blocks poetic that interrelate by a common theme or other resource or literary technique thus configuring a structural arrangement of the whole book.
