Exodus 10:9

Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.

Gather the people together, men, and women, and children, and thy stranger that is within thy gates, that they may hear, and that they may learn, and fear the Lord your God, and observe to do all the words of this law: And that their children, which have not known any thing, may hear, and learn to fear the Lord your God, as long as ye live in the land whither ye go over Jordan to possess it.

And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, The Lord God of the Hebrews hath met with us: and now let us go, we beseech thee, three days’ journey into the wilderness, that we may sacrifice to the Lord our God.

And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the Lord God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.

Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;

And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.

Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the Lord.

And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days’ journey into the desert, and sacrifice unto the Lord our God; lest he fall upon us with pestilence, or with the sword.

And Pharaoh called for Moses and for Aaron, and said, Go ye, sacrifice to your God in the land. And Moses said, It is not meet so to do; for we shall sacrifice the abomination of the Egyptians to the Lord our God: lo, shall we sacrifice the abomination of the Egyptians before their eyes, and will they not stone us? We will go three days’ journey into the wilderness, and sacrifice to the Lord our God, as he shall command us. And Pharaoh said, I will let you go, that ye may sacrifice to the Lord your God in the wilderness; only ye shall not go very far away: intreat for me.

And all the house of Joseph, and his brethren, and his father’s house: only their little ones, and their flocks, and their herds, they left in the land of Goshen.

And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.

And on the fifteenth day of the seventh month ye shall have an holy convocation; ye shall do no servile work, and ye shall keep a feast unto the Lord seven days:

Honour the Lord with thy substance, and with the firstfruits of all thine increase:

Both young men, and maidens; old men, and children: Let them praise the name of the Lord: for his name alone is excellent; his glory is above the earth and heaven.
