“And it will be when your children say to you, ‘What is the meaning of this new slavery to you?’

“And you shall tell your son on that day, saying, ‘It is because of what Yahweh did for me when I came out of Egypt.’

“And it will be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘With a strong hand Yahweh brought us out of Egypt, from the house of slavery.

“For this reason You are great, O Lord Yahweh; for there is none like You, and there is no God besides You, according to all that we have heard with our ears.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.

Recount about it to your sons, And let your sons recount about it to their sons, And their sons to the next generation.
