This belief stems from the legend that in the beginning God had three sons and that to each he gave one gift. The first son received an arrow for hunting, the second received a hoe for cultivating, and the third son received a stick for herding cattle.
Šis ticējums ir cēlies no leģendas: iesākumā Dievam bijuši trīs dēli, un katram viņš devis dāvanu — pirmais saņēmis bultu medībām, otrais kapli zemes apstrādāšanai un trešais nūju, lai ganītu liellopus.
