But no one may consecrate a firstborn of the livestock, because a firstborn belongs to the LORD. Whether it is an ox or a sheep, it is the LORD’s.
Jewish Publication Society of America Version (JPS1917) - Leviticus 27:26 >Howbeit the firstling among beasts, which is born as a firstling to the LORD, no man shall sanctify it; whether it be ox or sheep, it is the LORD'S.
