Kutoka 13:2

“Niwekeeni wakfu kila mzaliwa wa kwanza wa kiume. Kila mtoto wa kwanza aliye kifungua tumbo miongoni mwa Waisraeli ni mali yangu, akiwa wa mwanadamu au wa mnyama.”

Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.
