Exodus 34:24-26 American Standard Version (ASV)
24 For I will cast out nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou goest up to appear before Jehovah thy God three times in the year.
25 Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the passover be left unto the morning. 26 The first of the first-fruits of thy ground thou shalt bring unto the house of Jehovah thy God. Thou shalt not boil a kid in its mother’s milk.
