Cânticos 8

6 Set me as a seal upon thine heart as a sign upon thine arm; for love [is] strong as death; jealousy [is] hard as Sheol; the coals thereof [are] coals of fire, [which have a] most vehement flame.

7 The many waters cannot quench love, neither can the rivers drown it; if [a] man would give all the substance of his house for this love, it would certainly be despised.
