The Christian Passover memorializes Israel's deliverance from slavery and recalls Jesus' sacrifice, as a Passover lamb, for our sins and the sins of all humans who would ever live.
The Feast of Unleavened Bread is a period that comes right after Passover where no leavened bread or leavening is to be eaten. In fact, God commands that leaven be removed completely from where a person lives.
Jesus Christ willingly came down from heaven and took the form of a man to die for our sins. Though he was hated and rejected by many, he endured to the end of his life to become the perfect sacrifice and to reconcile man to God.
5 But because of our sins he was wounded, beaten because of the evil we did . . . (Isaiah 53, TEV)
53 Jesus, therefore, said to them, 'Verily, verily, I say to you, If ye may not eat the flesh of the Son of Man, and may not drink his blood, ye have no life in yourselves; 54 he who is eating my flesh, and is drinking my blood, hath life age-during, and I will raise him up in the last day; 55 for my flesh truly is food, and my blood truly is drink; 56 he who is eating my flesh, and is drinking my blood, doth remain in me, and I in him. (John 6:53-57, YLT)
The Hebrew word pesach, which is Strong's Concordance #6453, means to pass over or a passing over.
