Exodus 10:25-27

New Century Version

²⁵ Moses said, “You must let us have animals to use as sacrifices and burnt offerings, because we have to offer them to the Lord our God. ²⁶ So we must take our animals with us; not a hoof will be left behind. We have to use some of the animals to worship the Lord our God. We won’t know exactly what we will need to worship the Lord until we get there.”

²⁷ But the Lord made the king stubborn again, so he refused to let them go.
