'For Us' in the Bible

And ye answered me, and said, The thing which thou hast spoken is good for us to do.

And ye came near to me every one of you, and said, We will send men before us, and they shall explore the land for us, and bring us word again by what way we must go up, and into what cities we shall come.

From Aroer, which is by the brink of the river of Arnon, and from the city that is by the river, even to Gilead, there was not one city too strong for us: the LORD our God delivered all to us:

It is not in heaven, that thou shouldst say, Who shall ascend for us to heaven, and bring it to us, that we may hear it, and do it?

Neither is it beyond the sea, that thou shouldst say, Who shall go over the sea for us, and bring it to us, that we may hear it, and do it?
