'Let Us' in the Bible

"Then all of you approached me, and [you] said, 'Let us send men {before us}, and let them explore the land for us, and let them bring back {a report} to us [concerning] the way that {we should take} [and concerning] the cities that we shall come to.'

But Sihon king of Heshbon was not willing to let us cross through his [territory] because Yahweh your God hardened his spirit and {made him obstinate} {in order to give him} into your hand, {just as he has now done}.

and the sign or the wonder comes [about] that he spoke to you, {saying}, 'Let us go after other gods (those whom you have not known), and let us serve them,'

"If your brother, the son of your mother or your son or your daughter {or your wife whom you embrace} or {your intimate friend} in secrecy {says}, 'Let us go and let us serve other gods!' [gods] that you and your ancestors have not known,

{worthless men} have gone out from your midst and have seduced the inhabitants of their town, {saying}, 'Let us go and serve other gods!' whom you have not known,
