Exodus 22:27-30

27for that is his only covering; it is his clothing for his body. In what shall he sleep? And when he cries to Me [for help], I will hear him, for I am compassionate and gracious.

28“You shall not curse God, nor curse the ruler of your people [since he administers God’s law].

29“You shall not delay the offering from your harvest and your vintage. You shall give (consecrate, dedicate) to Me the firstborn of your sons.

30You 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.
