'Children's' in the Bible

So these nations were fearing Yahweh, but they were serving their idols, as were their children and their children's children; as their ancestors did, they [are] doing until this day.

He denounces friends for reward, so his children's eyes will fail.

If I had said, "I will speak thus," behold, I would have acted treacherously against your children's generation.

But the loyal love of Yahweh [is] from everlasting to everlasting on those who fear him, and his righteousness to [their] children's children,

and that you may see your children's children. [May] peace [be] upon Israel.

"And as for me, this [is] my covenant with them, says Yahweh: my spirit that [is] upon you, and my words that I have placed in your mouth shall not depart from your mouth, or from the mouths of your {children}, or from the mouths of {your children's children}," says Yahweh, "from now on and forever."
