'Let Us' in the Bible

then drew they near unto Zerubbabel, and unto the ancestral chiefs, and said unto them, Let us build with you, for, like you, we seek your God, and, unto him, have, we, been sacrificing since the days of Esar-haddon, king of Assyria, who brought us up hither.

Now, therefore, let us solemnize a covenant unto our God - to put away all the women and such as have been born of them, in the counsel of my lord, and them who tremble at the commandment of our God, - and, according to the law, let it be done.
