'For Us' in the Bible

You came near to me everyone of you, and said, "Let us send men before us, that they may search the land for us, and bring us word again of the way by which we must go up, and the cities to which we shall come."

From Aroer, which is on the edge of the valley of the Arnon, and the city that is in the valley, even to Gilead, there was not a city too high for us; the LORD our God delivered up all before us:

It is not in heaven, that you should say, "Who shall go up for us to heaven, and bring it to us, and make us to hear it, that we may do it?"

Neither is it beyond the sea, that you should say, "Who shall go over the sea for us, and bring it to us, and make us to hear it, that we may do it?"
