In the OLD Testament, Sacrifice of the Passover Lamb
Exodus 12:2-6
This month shall be unto you the beginning of months: it shall be the first month of the year to you.
Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house:
And if the household be too little for the lamb, let him and his neighbour next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb.
Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats:
(passover)
And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening.
In the NEW Testament, Sacrifice of the Passover Lamb
Matthew 21:5-9
Tell ye the daughter of Sion, Behold, thy King cometh unto thee, meek, and sitting upon an ass, and a colt the foal of an ass.
And the disciples went, and did as Jesus commanded them,
And brought the ass, and the colt, and put on them their clothes, and they set him thereon.
And a very great multitude spread their garments in the way; others cut down branches from the trees, and strawed them in the way.
And the multitudes that went before, and that followed, cried, saying, Hosanna to the son of David: Blessed is he that cometh in the name of the Lord; Hosanna in the highest.
