God instructed the people of Israel to always remember the Passover, and to celebrate a remembrance of the event each year. And He told them to tell their children about it.
“It is a night to be observed for the LORD for having brought them out from the land of Egypt; this night is for the LORD, to be observed by all the sons of Israel throughout their generations.” ~ Exodus 12:42
“‘And you shall tell your son on that day, saying, ‘It is because of what the LORD did for me when I came out of Egypt.’ And it shall serve as a sign to you on your hand, and as a reminder on your forehead, that the law of the LORD may be in your mouth; for with a powerful hand the LORD brought you out of Egypt. Therefore, you shall keep this ordinance at its appointed time from year to year… And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘With a powerful hand the LORD brought us out of Egypt, from the house of slavery. And it came about, when Pharaoh was stubborn about letting us go, that the LORD killed every first-born in the land of Egypt, both the first-born of man and the first-born of beast. Therefore, I sacrifice to the LORD the males, the first offspring of every womb, but every first-born of my sons I redeem.'” ~ Exodus 13:8-10, 14-15
They were to always remember, never forget, what the LORD had done for them. It was to be freely talked about with their children. And they were to redeem their own first-born children by devoting them to the LORD.
We, too, can celebrate a remembrance of our own Passover, Jesus, “the Lamb of God who takes away the sin of the world!” ~ John 1:29. We have been redeemed by the blood of the Lamb, and these words should be in our mouth, shared with others, beginning with our own families. Then, “go tell it on the mountain!” 🙂
