'Let Us' in the Bible

then they came to Zerubbabel and to the chief of the fathers, and said to them, Let us build with you, for we seek your God, even as you. And we have sacrificed to him since the days of Esar-haddon king of Assyria, who brought us up here.

And now let us make a covenant with our God to put away all the women, and such as have been born of them, according to the counsel of the Lord, and of those who tremble at the commandment of our God. And let it be done according to the Law.
