'Alone' in the Bible

Is not this what we told thee in Egypt, when we said, Let us alone, and we will serve the Egyptians? For it had been better for us to serve the Egyptians than to die in the wilderness.

And Moses' father-in-law saw all that he did with the people, and said, What is this thing which thou art doing with the people? why dost thou sit alone, and all the people are standing by thee from morning to evening?

Thou wilt be quite exhausted, both thou and this people that is with thee; for the thing is too heavy for thee: thou canst not perform it alone.

If he came in alone, he shall go out alone: if he had a wife, then his wife shall go out with him.

If his master have given him a wife, and she have borne him sons or daughters, the wife and her children shall be her master's, and he shall go out alone.

And let Moses alone come near Jehovah; but they shall not come near; neither shall the people go up with him.

And now let me alone, that my anger may burn against them, and I may consume them; and I will make of thee a great nation.
