'Forty' in the Bible

About forty thousand armed for fighting crossed [over] before the presence of Yahweh to the plains of Jericho for battle.

For forty years the {Israelites} traveled in the wilderness until all the nation, the warriors that left Egypt, perished, because they did not listen to the voice of Yahweh. To them Yahweh swore that they would not see the land that he swore to their ancestors to give to us, a land flowing with milk and honey.

{I was forty years old} when Moses Yahweh's servant sent me from Kadesh Barnea to spy out the land, and I returned {with an honest report}.
