'Let Us' in the Bible

Then they came to Zerubbabel, and to the chief of the fathers, and said unto them, Let us build with you: for we seek your God, as ye do; and we do sacrifice unto him since the days of Esarhaddon king of Assur, which brought us up hither.

Now therefore let us make a covenant with our God to put away all the wives, and such as are born of them, according to the counsel of my lord, and of those that tremble at the commandment of our God; and let it be done according to the law.

Let us appoint our rulers therefore in all the congregation, that all they which have taken strange wives in our cities, may come at the time appointed - and the elders of every city and their judges with them - till the wrath of our God be turned away from us for this offense."
