Exodus 22:29-31

Young's Literal Translation

²⁹ `Thy fulness and thy liquids thou dost not delay; the first-born of thy sons thou dost give to Me;

³⁰ so thou dost to thine ox, to thy sheep; seven days it is with its dam, on the eighth day thou dost give it to Me.

³¹ `And ye are holy men to Me, and flesh torn in the field ye do not eat, to a dog ye do cast it.
