Leviticus 23:33-37 KJV
And the Lord spake unto Moses, saying,  Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the Lord.  On the first day shall be an holy convocation: ye shall do no servile work therein.  Seven days ye shall offer an offering made by fire unto the Lord : on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the Lord : it is a solemn assembly; and ye shall do no servile work therein.  These are the feasts of the Lord, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the Lord, a burnt offering, and a meat offering, a sacrifice, and drink offerings, every thing upon his day:
Galatians 6:6-12 KJV
Let him that is taught in theY word communicate unto him that teacheth in all good things.  Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.  For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.  And let us not be weary in well doing: for in due season we shall reap, if we faint not.  As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.  Ye see how large a letter I have written unto you with mine own hand.  As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.
