'Religious' in the Bible

"And this day will become a memorial for you, and you will celebrate it as a religious feast for Yahweh throughout your generations; you will celebrate it as a lasting statute.

{And} when you come into the land that Yahweh will give to you, as he said, you will keep this {religious custom}.

{And} when your children say to you, 'What [is] this {religious custom} for you?'
