'Within' in the Bible

From these, [the people of] the coastlands of the nations were separated and spread into their lands, every one according to his own language, according to their constituent groups (families), and into their nations:

These are the families of the sons of Noah, according to their descendants, by their nations; and from these [people] the nations were separated and spread abroad on the earth after the flood.

But the children struggled together within her [kicking and shoving one another]; and she said, “If it is so [that the Lord has heard our prayer], why then am I this way?” So she went to inquire of the Lord [praying for an answer].

within three more days Pharaoh will lift up your head (present you in public) and restore you to your position; and you will [again] put Pharaoh’s cup into his hand just as [you did] when you were his cupbearer.

within three more days Pharaoh will lift up your head and will hang you on a tree (gallows, pole), and [you will not so much as be given a burial, but] the birds will eat your flesh.”
