Exodus 23:19 ASV

¹⁷  Three times in the year all thy males shall appear before the Lord Jehovah.

¹⁸  Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the fat of my feast remain all night until the morning.

¹⁹  The first of the first-fruits of thy ground thou shalt bring into the house of Jehovah thy God. Thou shalt not boil a kid in it mother's milk.

²⁰  Behold, I send an angel before thee, to keep thee by the way, and to bring thee into the place which I have prepared.

²¹  Take ye heed before him, and hearken unto his voice; provoke him not; for he will not pardon your transgression: for my name is in him.
