'Heaven' in the Bible

for in six days Yahweh made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore Yahweh blessed the Sabbath day, and made it holy.

Yahweh said to Moses, "This is what you shall tell the children of Israel: 'You yourselves have seen that I have talked with you from heaven.

It is a sign between me and the children of Israel forever; for in six days Yahweh made heaven and earth, and on the seventh day he rested, and was refreshed.'"
