Exodus 22:28-31

“You shall not curse God, nor curse the ruler of your people [since he administers God’s law]. [Acts 23:5] “You shall not delay the offering from your harvest and your vintage. You shall give (consecrate, dedicate) to Me the firstborn of your sons. [Ex 34:19, 20] You shall do the same with your oxen and with your sheep. It shall be with its mother for seven days; on the eighth day you shall give it [as an offering] to Me. “You shall be holy men to Me; therefore you shall not eat meat [from any animal] that has been torn to pieces [by predators] in the field; you shall throw it to the dogs.
