Obatalá had two sons and put them in the charge of different guides. Layebe Omo Lalara stayed with Elegba, so that Elegba would guide him and teach him; Ifa Yewa stayed with Shangó, for the same purpose. He sent the four of them together.
Shangó and Elegba settled in the land of Oni Fawa, a place of hills and dense bush. Shangó informed Obatalá that Ifa Yewa would live above, on the hill, and Elegba informed him that Layebe would live below, among the undergrowth.
Time passed and one day Obatalá announced: “I will go and see how my sons are doing; they must be well guided by now.” Shangó spotted him from the top, called Ifa Yewa to propose that they go out and mark Obatalá's path with cascarilla and with slug shells. They came down and told Elegba and Layebe. Shangó immediately took Elegba's cowbell, and all began to ring it and to sing.
Obatalá heard the voices of Shangó and Elegba and was very glad. He saw Ifa Yewa tracing the path with cascarilla and slugs, and also Layebe pouring hot water to kill the slugs. Ifa Yewa, at the same time, was pouring cold water mixed with cascarilla on them, so that not all of them died. At first this bothered Obatalá, but then, seeing that the slugs were being saved by Ifa Yewa's cold water and cascarilla, he became pleased.
On arriving where Shangó and Elegba were, they greeted him with the moforibale and served him a banquet of beef, and also cascarilla and cocoa butter. Layebe, thinking that it would anger Obatalá, added palm oil to it; however, Obatalá was glad. He told Shangó that he was very grateful to all of them and to his sons, and asked them to wait for him outside, since he wanted to leave in their company.
They went out onto the road. While Elegba and Shangó walked on, Obatalá took a cowbell and an agogo and began to sing. Then he took Layebe aside and spoke to him alone: “From now on, the only thing that sprouts in you is envy. A day will come when you are left alone in this land, and all who imitate you will end up the same.” So he cursed him. Next he took out a sack of mice and set them free. He warned Ifa Yewa not to kill them because they would be his salvation, that he had his blessing and that he must not be afraid of them. Then Obatalá left.
Layebe knew an omologu living in the land of Omoniwa. He went to see him and confessed that he wanted to wipe out his brother Ifa Yewa. The omologu prepared a sorcerer's pot, an ikoko ogu, and gave it to him with these instructions: he was to dig a deep hole under the hill where Ifa Yewa lived and light many lamps there, for that would destroy him.
Ifa Yewa found out about everything. With his odeban at hand, he poured water and put out the lamps one by one. Meanwhile, the loose mice went into the caves and began to breed. Seeing the hill turned into a hollow, Ifa Yewa became frightened; he lay down to sleep and dreamed that he must go to where Obatalá and Shangó were.
He woke up and ran toward them, scattering cascarilla and slugs along the way and calling Obatalá. When he reached Obatalá, Shangó and Elegba, the three received him happily. Obatalá, in tears, told him to wait for news.
It rained for three days, and the hill of Omoniwa collapsed. Just then the omologu and Layebe were doing a bad work with palm oil, and both of them perished. On receiving the news, Obatalá pronounced: “This is how every envious person ends who wants to achieve what is not his.” He ordered Shangó and Elegba to put Ifa Yewa to safety with plenty of palm oil, that he should never again inhabit the summit of the hill and that he should always count on them.
Ifa Yewa answered Obatalá and Shangó that, since they were his fathers, he wished them to live at his side so that he might find his happiness. And so it was done.
