John Gill Commentary Exodus 10:25

"And Moses said, Thou must also give into our hand sacrifices and burnt-offerings, that we may sacrifice unto Jehovah our God." — Exodus 10:25 (ASV)

And Moses said, you must give us also sacrifices and
burnt offerings
Sheep, rams, and goats for sacrifices, and oxen for burnt offerings; and that of his own, as Jarchi interprets it; but rather the meaning is, that besides having their little ones with them, they must be allowed also to take their cattle for sacrifices and burnt offerings: that we may sacrifice unto the Lord our God ;
might have wherewith to offer up in sacrifice to him as he shall require.
