'Waiting' in the Bible

Now when the king of Ai saw it, he got up quickly and went out to war against Israel, he and all his people, to the slope going down to the valley; but he had no idea that a secret force was waiting at the back of the town.

And the sun was at rest and the moon kept its place till the nation had given punishment to their attackers. (Is it not recorded in the book of Jashar?) So the sun kept its place in the middle of the heavens, and was waiting, and did not go down, for the space of a day.

But do you, without waiting, go after their army, attacking them from the back; do not let them get into their towns, for the Lord your God has given them into your hands.
