'Let Us' in the Bible

And then ye came unto me every one and said, 'Let us send men before us, to search us out the land and to bring us word again, both what way we shall go up by, and unto what cities we shall come.'

But Sihon, the king of Heshbon, would not let us pass by him; for the LORD thy God had hardened his spirit and made his heart tough because he would deliver him into thy hands as it is come to pass this day.

and that sign or wonder which he hath said come to pass - and then say, 'Let us go after strange gods which thou hast not known, and let us serve them':

If thy brother, the son of thy mother, or thine own son or thy daughter or the wife that lieth in thy bosom or thy friend which is as thine own soul unto thee, entice thee secretly, saying, 'Let us go and serve strange gods which thou hast not known nor yet thy fathers,

that certain being the children of Belial are gone out from among you and have moved the inhabiters of their city, saying, 'Let us go and serve strange gods which ye have not known.'
