The name that is transliterated as “Perez” in English means “breach,” “bursting through” (see Genesis 38:29). (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that recaptures the story in Genesis 28, where the baby Zerah pulled his hand back, and his brother Perez came out first as the substitute, representing a situation in which a person arrives and takes the place of the baby Zerah.
