'Once' in the Bible

"Then the LORD told me, "Get going! Go down from here at once! Your people whom you brought out of Egypt have become corrupt. They have turned quickly from the way that I commanded them, and have cast an idol for their use.'

When I stood on the mountain for 40 days and 40 nights as I did the first time, the LORD listened to me once again. The LORD was not willing to destroy you.
